Numerous studies have attempted to observe and understand a range of behavior in sharks; however there remain many unanswered questions. Sharks are notoriously difficult to observe and the costs associated with satellite tracking have led to a relative dependence on acoustic telemetric tools to achieve research goals. This provides data on spatio-temporal elements well but defines actual behavior poorly i.e. we know where an animal is and at what time but not what it is doing. Accelerometer technology combined with traditional acoustic telemetry allows for a more precise study of natural behavior than has previously been attainable. This project aims to identify and delineate a range of fine-scale behaviors of Bimini lemon sharks in space and time, thus producing ‘a day in the life of a shark’.
1. How do juvenile and sub-adult lemon sharks behave on a day to day basis? What patterns in activity do they display and what factors drive these observed patterns i.e abiotic and biotic factors ?
2. What predatory tactics do lemon sharks employ? How often do they hunt and how successful are they?
3. How important is predator avoidance in the decision making process of young lemon sharks? How often do individuals attempt to avoid predators?
