Most of the sharks spotted in the area are juveniles — despite their size, the great whites are only up to about 6 years old and very inexperienced hunters. Some great white sharks are getting ...
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 ...

[3] The first dorsal fin originates over the bases of the large pectoral fins, while the second dorsal fin originates slightly anterior to the free rear tips of the pelvic fins.
During the day, these sharks often form aggregations of 5–20 individuals near coral reef drop-offs, and then split up in the evening as the sharks begin to hunt.
