Nurse sharks are an important species for shark research. [3] They are robust and able to tolerate capture, handling, and tagging extremely well. [4] As inoffensive as nurse sharks may appear, they are ranked fourth in documented shark bites on humans, [5] likely due to incautious behavior by divers on account of the nurse shark's calm ...
They may be found in either small shoals or alone. Despite their large size and threatening appearance, basking sharks are not aggressive and are harmless to humans. The basking shark has long been a commercially important fish as a source of food, shark fin, animal feed, and shark liver oil.
Lemon sharks, therefore, select warm-water habitats to maintain optimal metabolic levels. They are believed to avoid areas with thick sea grasses because they make finding prey more difficult. [15] Lemon sharks tend to live in or near shallow-water mangroves, which are often the nursery areas of several species of fish. The data gathered about ...
