Galapagos Shark

Notes:

Sharks are Cartilagous fish that lack gas-filled swim bladders thus they sink if they stop swimming. One of the main reasons sharks are such effective predators is their keenly attuned senses such as directional sense of smell, very acute sense of hearing, acute eyesight, taste, and it also possess other senses that does not seem to be fully understood such as electroreception, and lateral lines. None of the shark's sense organs would be adequate for effective hunting but the combination of all these senses make the shark an incomparable predator. The sharks have pretty cool teeth! The upper teeth are stout and triangular in shape, while the lower teeth are narrower; both upper and lower teeth have serrated edges. When a sharks teeth is worn or broken it gets replaced by a new sharper teeth. In some sharks, such as the great white, these teeth are arranged in several rows but I do not know if that is the case for this one. Unprovoked shark attack seem to be extremely rare, from what I have hear and read, looks as if shark attack occurs when it confuses a scare swimmer with a small bank of fish. In any case, it is better slowly move away from them or as in my case remain inside your tour cage.
