Evolution of a Sharklabber



© Chris Bolte 2016



Trust is the word that comes to mind.


Almost everything about the situation is normal. I have a scuba tank on my back, one hand pressed over my mask and regulator while my other hand grips my weight belt. I have my eyes on our boat captain, waiting for the captain to give me the signal to tip backwards off the gunwale into the crystal blue water of Tiger Beach, a dive site 20 miles off the coast of Grand Bahama. As air gently rasps through my regulator, I’m a little bit surprised how calm I feel, given the circumstances. After all, there are about 20 adult lemon sharks circling at the surface, not to mention the sharks that are lurking below.


I first came to the Bimini Biological Field Station Foundation, a facility specializing in elasmobranch research in October of 2014 as a green volunteer. In the following months I was introduced to various research techniques, ranging from tracking sharks using acoustic receivers to capturing them with modified fishing techniques and collecting all types of data from them. Following my time as a volunteer, I was offered a position as an assistant manager, a position that I eagerly accepted.


All volunteers undergo training so that they are comfortable using GPS, tying knots, piloting our small boats, along with other Sharklab necessities. Among the most exciting of these classes is shark handling, where you venture out to semi-captive pens with the other volunteers to learn how to safely handle juvenile lemon sharks. For a new volunteer, stepping into a pen with 6 sharks seems like less than stellar idea, though volunteers quickly learn that the only interest that these sharks have in people is actively avoiding them. The sharks are not aggressive and pose almost no risk of delivering an unprovoked bite.

Perched on the side of the boat, I focus on this very experience. Though the sharks that are circling me are same species as the sharks in the pen, instead of being 60 centimeters, these sharks are closer to 250 centimeters. Alarmingly, these sharks are on the small end of the spectrum for what we are anticipating. Nonetheless, I remember how little the baby lemon sharks were interested in me, and hope that sort of behavior continues to be exhibited well into maturity.


The captain nods his head to me, and I tip backwards off the boat. The sensation that I feel in those minutes of anticipation followed by a quarter second of falling is more than just that, more than an anticipatory period. It is a moment that represents a year of immersion in a world of water, science, and sharks. A feeling of serenity, a void that formerly would have been occupied by fear and agitation.


Unsurprising, the first thing that I notice as I plunge into the water is exactly what you would expect. Sharks, so numerous that they take up more of my field of vision than the water does. They jostle and bump each other to get out of my way as I immediately begin to descend.


As I sink towards the bottom, the water begins to take a more sinister appearance. The lemon sharks milling about the surface are replaced by dark blue water, and as my knees touch the sand, the sharks that we have come all this way to see begin to arrive. They emerge from the water, slowly, confidently. Unmistakable in their appearance, with black vertical blotches punctuating their flanks, the tiger sharks approach us. They look small at first, approaching us from the sea grass. As they get closer and closer, the sheer magnitude of this predator becomes evident.  The largest of the three is probably about 15 feet long, thicker around than an oak barrel. Black eyes gaze at you, seemingly apathetic as these gigantic sharks make easy passes past us, circling. They are nothing short of gorgeous, their species easily ranking among the most impressive predators in the world.

It seems a culmination of my experiences at the Sharklab, a test of whether or not I have gained some measure of composure interacting with these creatures. Except for the size discrepancy, it’s an experience remarkably similar to those first few days with the baby lemon sharks. Trusting that the sharks are going to go about their business while I sit in silent awe. Unsurprisingly the tigers continue to cruise around, exhibiting nothing more than a passing interest in me and the other divers, never threatening. Though I always remain cautious, I feel like the trust that I had given to these predators is well placed.


I only wish that they could say the same of us.

   "When in Rome, do as the Romans."

My Experience as a Volunteer in the Sharklab

by Maria Paz Gutierrez


Somebody once told me that proverbs reflect the way people of that culture think about the world.  A well-known proverb  of English-speaking cultures is "When in Rome, do as the Romans",  meaning that you have to act in the same way as the people around you.

For me, a foreign girl coming from Chile (a tiny third-world country) to the Famous Sharklab, inhabited by people coming from first-world countries (U.S.A, France, Australia, Canada and England), understanding and practice this proverb has been very useful.

Seeing a rice maker and a drone for the first time and watching BBC documentaries with actors that were in the Lab only hours before at first took me out of my comfort zone. This was heightened by the fact that I am still learning how to speak English, so I really didn´t understand anything about the house rules, duty list, packing practices , etc. The good thing is that any time that I made a mess, I would just say "I do not speak English."

Now that I have been here for 24 days, I am almost one Roman more, almost reaching a first-world understanding.... thinking about the postgraduate program in which I will enroll in two more years, the model and price of  the GPS that I will deploy with acoustic tag receivers to find sharks easily, or maybe even getting my own drone to find them without getting out of the boat.

Only a few weeks have passed and I have learned a lot more than what I was expecting, not only in a "fun-shark-work" way, but in a "do-and-fix-everything-that-you-will-need-to-do-the-fun-shark-work" way, from making a shark pen (see Alex McInturf blog: "When life gives you lemons...take DNA) and fixing gillnets to tagging tigers sharks and swimming with hammerhead sharks. This is a once-in-a-lifetime great opportunity with genius Romans, living, imitating and trying to understand them. What a great experience!

Home Economics with the Shark Lab



When referring to the act of sewing, most have a very classic cultural image in mind: perhaps cross-stitch, needlepoint, or maybe weaving a tapestry on a loom. Thanks to my most recent experience here at the Sharklab, it is unlikely that my definition will match that of general society for a quite a long time after my return to civilization. A few days ago, staff member Anthony handed me, not a needle and thread, but a broken stick and spool of rope as we stood on the beach, confronted by a stretch of green mesh thirty-seven meters long. Upon closer inspection, my team of volunteers and I could tell that years of use had taken their toll – the mesh was spotted with tears and gaping holes of all sizes, held together by spare pieces of old line and the occasional zip tie. As the sun sporadically peaked through a layer of clouds, we learned that our task for the afternoon was to completely dissemble the patches, removing any remaining ties or lines. From there, we were to move on to our ultimate goal: a new shark pen. 


            As the first hours passed, we bent over with intense concentration, our fingers fumbling with knots and clipping with reckless abandon. Thirty-seven meters, however, began to stretch longer and longer, the knots more and more complex, as the sun began to set and the mosquitoes attacked our vulnerable ankles. By the end of the day, we saw before us now two pieces of mesh, each riddled with holes that seemed even larger. In the waning light, with the smell of dinner wafting from the Lab across the road, Anthony then taught us to sew, overlapping the two pieces lengthwise and securing them with an alternating loop and knot pattern. By the time the dinner bell rang, our loom barely had its first strands. 


            For the next several days, the rain and wind continued a concerted effort to impede our work, but for Sharklab personnel, weather is not a worthy adversary. As the drops fell on our faces we transported our mesh to the yard, sewing morning and afternoon. Those who chose to stand felt the soreness of hamstrings too long stretched, while those seated on boat cushions were forced into the occasional head roll to relieve the growing stiffness in the upper back. Amidst laughing chatter and soft music, the minutes and hours blended into days, and the mesh began to sport bright white lining around newly repaired patches. The sewing continued until evening, four days after we had begun. I tied my last bowline and took my last stroll down what I had begun to consider my very own pen mesh, bending down and testing for strength in the line as I went. By the time I rose, satisfied, I had essentially forgotten the purpose behind the sewing; that is, until I heard the plan for the next day. It was time to build the pen.


            Under most normal circumstances, experienced pen builders can complete the task in a morning or afternoon. “Normal circumstances,” however, were too much to hope for in this case. Naturally, I was assigned to the pen-building crew, presumably because this had become my adopted project. We were directed by the fearless Chris Bolte, who seemed to know what he was doing, though after a mishap with rebar placement, we began to assail him for his questionable leadership. The mocking continued, bouncing between volunteers and Chris alike, heightening as the sun tried to warm the chilly air of the late morning. By lunchtime, we had only assembled half the pen mesh. Our afternoon was even busier, and somehow more filled with testosterone-fueled jokes. By the time we settled into a rhythm and finished tightening the security around the net, we were joined by three more volunteers, some of whom began the process of moving the baby lemon sharks and newly acquired ray from the old pen to the new. From the new pen location in the shallows, we could hear singing and laughter as paddleboards were loaded with cinder blocks, rebar, and tuna clips, floating alongside tubs of animals in the transition. The sun was sinking on our fifth day by the time we shed our wetsuits and ran inside for coffee, tea, and a hot dinner. Before we left, however, I stood in the new pen for a few minutes. As the water settled, I looked down. Two of the three baby lemons were snaking around my ankles. One had a small dark spot on its head. The ray would occasionally smack its wing on the surface of the water along the interior mesh, as if admiring our handiwork. Much as one might admire a sewn pillow, a knitted scarf, or a woven rug, I can’t imagine any better feeling than knowing that I have created a home, one that serves as a classroom as much as a refuge.

“My jacket is wet.” “My SHOES are wet!” “It is well and truly coming down out there.”

 These three phrases almost completely summarize my first week at the Bimini Shark Lab. Words without context, however, can be misleading. I’m surrounded by the usual morning bustle that characterizes rainy days here at the station – there are volunteers half-clad in wetsuits, prepared to depart at any moment, staff members staring at radars to determine when there will be a break in the weather, and a few pitbulls wrestling over a chew toy in the hallway. It has been ten days since my arrival, and I have yet to have an “off day.” Weekends truly don’t exist here; in fact, I can barely keep track of the time, much less the day, and dates only have meaning at the top of our data sheets. I arrived at the lab with the onset of the New Year with three new volunteers, just in time to work tirelessly with the rest of the crew (10 staff members, and 6 veteran volunteers) on a project that will provide critical data on the shark species that populate these waters.


 A few years ago, the lab deployed fifty acoustic receivers that collectively cover every marine area around both North and South Bimini. Twice a year since their initial establishment, they have been collected and then, following a massive data download, redeployed.  This is certainly no easy feat – each receiver cost roughly $1,300, and recollecting the installed units requires dropping a diver directly on top of the receiver’s exact coordinates. Then, of course, said diver must cope with factors entirely out of his or her control: visibility, current, or, as is the case today, unpredicted bouts of torrential downpour. Ideally the entire process takes place within 48 hours, but dark clouds rolled in during the early hours of this morning. Make no mistake, however, consideration for our personal comfort is not the cause for delay. In fact, I would argue that in addition to a collective passion for elasmobranchs, one of the major common characteristics embodied by every single person at this lab is a mildly insane willingness to sacrifice almost everything for the pursuit of knowledge. On the other hand, as researchers, we are nothing if not practical. We won’t be able to find the receivers in this weather.


Unfortunately, this research obstacle is fairly typical for this time of year. The cold fronts that hit the United States during the winter inevitably reach even the Bahamian islands, though they manifest themselves in slightly different ways. We fall victim to the weather’s capriciousness; already I’ve experienced the warmth of the sun on my back as we cruised across turquoise patches of water, only to don a sweatshirt in the overcast chill of the next morning. However, I have learned that these types of challenges unexpectedly bring out the very enthusiasm that defines the members of the Shark Lab. Our shoes may be wet, our jackets soaked, and our receivers left alone for the time being, but as we gradually disperse to find more weather-appropriate tasks, laughter and friendly chatter echo through our tiny home.    


My field of vision, already limited by my mask, narrows further as I focus on my camera’s screen through its underwater housing. Having to concentrate so hard means that I am temporarily oblivious to my immediate surroundings, so I’m somewhat startled when I look up from my camera and gaze into the cold eyes of a 3.6-metre (12-foot) great hammerhead shark Sphyrna mokarran. It’s so close I can count its teeth.



Believe it or not, this is actually a pretty normal winter’s day with the Shark Lab in Bimini and it is a critical component of our great hammerhead research project. These personal encounters enable us to get close enough to photograph the sharks while projecting two parallel laser beams onto their bodies. The lasers, set 20 centimetres (eight inches) apart, can be used to estimate the total length of individual sharks, giving us valuable life-history information. This technique, called parallel laser photogrammetry, has emerged as a simple, non-invasive method to estimate with a fair degree of accuracy the sizes of large marine species such as manta rays, whale sharks and great white sharks – essentially, any animal that is difficult to capture safely. 



In the water next to me, managing the bait-filled container used to attract the hammerheads, is my good friend and colleague Jack Massuger. As the vortex of sharks swirls around him, he remains composed, sifting through the blockade of stubborn nurse sharks to gently coerce the hammerheads into exposing their sides to my camera. If a shark’s side is anything but perpendicular to the twin green beams, it introduces an error of parallax. This means that, due to the angle between the photographer and the shark, the distance between the lasers will change, resulting in skewed length estimates. Getting perfect photos is a process that requires patience. We spend many dives and many hours with the hammerheads.

Using laser photogrammetry, paired with photo identification to distinguish between individuals, we are beginning to learn more about these enigmatic predators. How long are they spending in Bimini? Do they come back every year? Are these individuals sexually mature? Where were they before they came to Bimini, and where do they go when they leave? 



After a season of data collection, we know that more females visit than males, and many of the sharks are large enough to be sexually mature. Using photo identification, along with acoustic receiver arrays, we have been able to locate sharks that we see in Bimini in places like Key Largo, Virginia and the Bahamas’ Exuma Islands, which has helped to reveal their large-scale movement patterns. Listed as Endangered by the IUCN, the great hammerhead faces strong fishing pressure for its distinct, scythe-like fins. Our goal is to learn as much as we can about the species so that we can use this information to protect individuals wherever they travel.



As dusk falls and the light begins to fade, the dive feels like a scene from a science-fiction horror movie. Sharks emerge from the darkness, continuing to circle around us. Two bright green laser beams slice through the water as we record a few more measurements, persisting until it’s too dim to continue. As our air dwindles, we take a final few rasping breaths through our regulators and slowly ascend. It is calm, oddly serene to have these sharks pass within centimetres of us, elegant in their slow, rhythmic swimming. As I shut down the lasers and pass my equipment up to the boat, I can’t resist looking down one last time. Hammerhead sharks pass beneath us and then, one by one, begin to disperse. These laser measurements are important for our research and conservation, but there is something else, something sublime, about just watching these sharks fade gently into the sanctuary of the dark, blue water.

Although it was eight years ago, I still remember my first encounter with a sawfish as one of the most extraordinary experiences of my life. And, in light of our recent paper ‘Occurrence and habitat use of the Critically Endangered small tooth sawfish, Pristis pectinata in the Bahamas’ being accepted by the Journal of Fish Biology, I feel it’s appropriate to recollect that moment now.

The nets are anchored at the edge of the mangroves and pulled offshore, then set for 12 hours overnight and for six consecutive nights. The target species is the lemon shark, but every now and again something special makes an appearance.
Removing a lemon shark from a gillnet. Photo by © Charlotte Sams.  It was the first night of the North Bimini juvenile lemon shark tagging programme, 2007. I was leading a gill-net set on the western edge of the North Lagoon. The water was about one metre deep and the substrate was rocky with patches of sand. At about 11 pm, an hour or so past high tide, our team was on its usual 15-minute check, flashing the torch down the net as we putted alongside in our boat and viewed the water from the surface. Suddenly splash, struggle – a shark was tangled in the net, then another and a few metres later there was a bigger splash. Excitedly, within the space of 60 seconds all my team had launched themselves into the water to rescue our catch: two juvenile lemon sharks and a bonefish.

I motored slowly along the length of the net, inspecting it carefully and methodically. As I got closer to the mangrove edge, I noticed that a large section – about 15 metres – of the net had turned into a huge cloud of silt. I couldn’t see a thing. My first thought was adult lemon shark (yippee) and then I considered big nurse shark (oh no – the net would be destroyed). The Shark Lab frequently documents both species in shallow water during summer, either pupping or seeking mates, so it was possible that one had got tangled up.

Ecstatic, I roared at the top of my voice, ‘Oh my god, it’s a sawfish, we’ve caught a sawfish.’ Then I shouted down the radio, ‘We’ve caught a sawfish, a sawfish, woohoo.’ Wilson, one of the volunteers, answered, ‘You’re joking!’ ‘Do I sound like I am joking?’ I gasped.

Any normal person would have thought we had won the lottery or that a boat full of pirates’ treasure had got caught in our net. To us, this was the lottery – one of the rarest, most imperilled creatures in the ocean and we had the privilege of seeing it up close!

When it comes to personality studies in sharks, the bigger the sample size, the better. In the third issue of Save Our Seas magazine, you might have read about how we study personality in juvenile lemon sharks at the Bimini Biological Field Station (also known as the Shark Lab). Now let me tell you about the PIT project, which catches enough sharks for us to conduct rigorous personality studies.

Mention the PIT project to a Shark Lab alumnus and you’ll probably hear words like crazy, exhausting, hilarious and miserable. The project is all of that! It involves capturing, in gill nets and at night, the entire population of juvenile lemon sharks of two nurseries in Bimini, measuring each shark and tagging it with a PIT (Passive Integrated Transmitter). By numbers, the PIT project is: three gill nets, four teams, 12 nights, hundreds of sharks and millions of mosquitoes. It’s been carried out each year since 1995 and has provided the Shark Lab with some major findings, such as the first evidence of female sharks returning to their place of birth.

PIT 2015 was my first round. So what goes through the head of a first-timer? In the weeks leading up to the first PIT night, the excitement builds slowly but surely – just like the pens that will hold all the captured sharks. Seasoned Shark Labbers tell their stories (sometimes funny, sometimes scary) to the newbies. All the equipment is checked, double-checked and checked again by anxious staff members. The closest grocery store is raided by dozens of interns worried about grumbling stomachs during the long nights.

Then one day, finally, it’s time to go! The first set is done in a deliriously happy mood, teams betting on whose net will be the most successful (and whose will catch a smalltooth sawfish). Suddenly the first shark is captured, to resounding exclamations that can be heard in Miami. After a very busy first night, 15 wet-to-the-bones interns come home ecstatic about their adventure. But during the following nights grumpiness gradually replaces excitement. You need to be very positive to avoid being affected by the long, dark, cold hours, watching the number of sharks caught decrease each night, and the constant buzzing of bugs around you. Fortunately, the Shark Lab is a great group of friends. Every night hilarious games are played over the radio to keep everyone entertained and the home-crew dresses up to bring a delicious dinner that will warm hearts and bodies in the middle of the night.

After six long nights of fishing in one nursery, it is time for the PIT warriors to get a rest. A rest? Not really! All the nets need to be repaired, the equipment must be rechecked and everybody has to get ready for another six nights. The nights in the second nursery are similar to the previous ones, with the first being much busier than the rest. But this time everyone is ready, sleeping strategies are well established and all the crew are mentally prepared for the task ahead.

In 2015 we tagged a total of 196 sharks, more than half of which were captured during the first night in each nursery. PIT 2015 involved 22 people, who finished the adventure exhausted but incredibly proud and excited. Did I tell you that sample size is important in personality studies? Well, during PIT 2015 60 sharks were tested for sociability and exploration, and a subset of 36 were tested for neophilia and boldness as well, providing me with a huge amount of data. So far, thanks to the PIT project, more than 250 sharks have been tested for personality traits. At the Shark Lab, this is how we roll!

I love the ocean, the smell of the salty air and spray of the waves as the boat rocks through the water.  Despite growing up 800km from the nearest coastline it is when I am by the water, on the water or diving under the water that I am home. For my time at the Bimini Sharklab this  becomes more fact than fantasy. Even on the rare days when I’m not out on a boat tracking, setting gillnets, longlines or snorkelling, the ocean is at my doorstep and is my backyard.  It’s in this backyard and out on the water that the Sharklab lives up to its name.  There is rarely a day that goes by that I don't see a shark.  Currently my shark count is composed of lemon, nurse, blacktip, and tiger sharks  but I have been warned of the bull sharks that frequent the Alice Town Channel and that December brings with it schools of hammerheads.  Most sharks we catch require a work up, taking measurements, DNA and isotopepe samples and inserting one or more tags.  The first shark I tagged was  a blacktip shark.  We had brought him up along the starboard side of the boat facing into the current.  My colleague Marissa held the shark steady by his dorsal fin as Matt, the PhD candidate, talked me through the steps.  The steps were simple really, line up the tag at 45Ëš where the dorsal fin meets the body in the small dark incision Matt had made then give the casey tag loader a strong whack to insert the tag.  My hand shakes as we sway in the waves and what should be a relatively quick and easy task seems daunting and endless.  It’s funny how something as simple as Marissa regripping the shark and saying, “Don't worry, you got this” that allows me to still my hand and slide the tag into the proper position.  With a deep breath and one more rock of the waves I slam my hand down and give the tag a pop.  As Matt leans over to check that the tag is securely in place a huge grin appears on my face.  Marissa and I exchange excited looks as I half whisper half squeal that I just tagged a shark!  Excitement pulses through me while we finish the workup and release the shark and it fills me now just thinking about it.  There is still a little over two months left in my time here and despite any fowl weather, 4am wake ups or the constant looming threat of mosquitos, I look forward to ever chance go get out in the boats and the prospect of seeing and tagging another shark. 



Sixty-six years ago George Orwell portrayed in his novel ‘1984’ a fictional entity called “Big Brother” who is claimed to rule a totalitarian state, creating a society that is under total surveillance by the authorities. Citizens are constantly reminded of this by the slogan “Big Brother is watching you”, an aphorism which is omnipresent on screens. In modern human society, Big Brother is inherent to abuse of civil rights, specifically in terms of mass surveillance. As bad as this may seem for human populations, however, mass surveillance by telemetry is arguably the most important and potent tool ecologists and conservationists have to protect natural populations and their habitats in increasingly human-dominated land- and seascapes.

In early 2014, the Bimini Biological Field Station (BBFS) established our equivalent of ‘Big Brother’ – an extensive acoustic underwater listening array, placed strategically in Bimini’s diverse marine habitats to monitor the movements of sharks and rays, tagged with 10-year transmitters. Each animal’s tag broadcasts its acoustic signal, every 90s or so and if within range of a receiver (i.e. ~500m), its ID, date and time stamp are recorded. Data builds, from minute to hour to day, month to year across different tidal phases, seasons etc. For the next three years I will use this data to identify drivers of movement, habitat preferences, spatial hotspots and mechanisms of habitat partitioning for Bimini’s local shark and ray fauna.

Only a few months ago I arrived at the station as a Principal Investigator to lead this project and have recently summarized our last 18 months of data. Some 48 sharks and rays from 7 species were detected by Bimini’s “Big Brother”. Interestingly, my first exploratory analysis has revealed that some species show a diverse habitat range throughout Bimini (e.g. an adult lemon shark detected on 34 receivers), whilst movements of others (e.g. southern stingray: 7 receivers) are more confined. It also appears that some habitats off southwest Bimini likely function as important corridors or highways for shark movement, detecting 20-30+ individuals. Further, I excitingly received information of our sharks ‘making moves’ outside of our array. Two male nurse sharks were detected in Andros and Grand Bahama, as well as migrating lemon sharks between Jupiter (Florida), Bimini and Florida Keys.

Surveillance arrays like the one deployed in Bimini provide valuable information regarding behavior, habitat and space use of sharks and rays on small geographic scales. While this information is crucial for effective conservation of local habitats, information about movements on scales of areas, countries or even continents is paramount to protect the populations that occupy them to conserve them for generations to come. Hence, small receiver arrays are gradually becoming larger and connected to other receiver arrays, creating large geographic scale networks. So is mass surveillance all that bad? I guess it’s a matter of perspective.

What does one tropical storm, meeting the one and only Samuel Gruber, doing my first work up on a reef and nurse shark, my first shark dive, and learning how to fish for barracuda all have in common? Everything I have experienced during my first month living and working at the Bimini Biological Field Station (but believe me it doesn’t stop there).  The hardest part is verbally encompassing all these amazing events and letting you in on the magic that the shark lab offers. So where do we start?  

            Well it begins with thinking you and your coworkers might be slightly insane. You’re there in the middle of the sea, it seems that all you notice are your fins slowly dangling back and forth underneath you and our heart rate beginning to increase. But cautiousness doesn’t slip to far from consciousness.  You hold the line, prepare yourself, take notice of everyone else in the water, and wait for the bait to get thrown. And one by one they begin to arrive…

Five reef sharks showed up during my first shark dive. That was the first time I was in open water with a shark and it would take me .01 seconds to do it again. They swim around, agile, might come close enough to caress your fin but at the same time you just got close enough to touch theirs as well. Sure, I called my mom later in the week and told her I had been on a shark dive and it was entertaining to listen to her reaction, “What, are you guys insane?!” Yea maybe, but how can you do this job if you aren’t (at least partially)? But mainly it was about that sheer humbling feeling you get, the anxiety rush, and the amazement of being in the water with an animal that’s close to 430 million years old. To look at a living fossil, an evolutionary legend.  It’s not about the bragging rights.
