We pull her alongside the boat and work her up, measuring and taking DNA samples. At 153 centimeters she's too small for the casey tag, so we cut her loose right away. Jeremy Sterk gives the tiger shark a push to get it swimming. Licky Drake, lab manager, who's been working with sharks on Bimini for four years, says she was scared when they brought the bull up.

Some people would say bulls are the meanest sharks in the ocean. Great whites attack by sneaking up on prey and coming at it really fast, knocking it out of the water.

Bulls can also live in fresh water, which puts them in closer proximity to humans on a regular basis.
