Researchers at the Bimini Biological Field Station in the Bahamas study the biology of sharks and rays, and the role that these top predators play in the marine ecosystem. During a "work up" (pictured here), they collect biological data, such as length measurements, fin clips for DNA samples (to determine family genealogies), blood and muscle samples (to determine diet). In addition, they tag the sharks with a microchip similar to that used for domestic pets, and often with an acoustic tag. The latter sends out an acoustic signal that can be picked up by receivers around the island of Bimini and other parts of the world. This is done in order to study the behavior and movement patterns of individual sharks. The “Sharklab” offers research experience programs for anyone interested in gaining insight into the life of a marine biologist studying sharks.
This split-shot image was taken in the water next to the tiger shark, by using an underwater camera coupled with a fisheye lens. After the tiger shark was released it calmly descended back into the deep water of the Gulf Stream
