Green moray eels , normally nocturnal creatures, can be seen hiding in the coral. They are predators, with a large mouth and many sharp teeth. They lay in wait for their prey, striking quickly. However, they are not as aggressive as they appear. They don't have very good eyesight and aren't likely to attack unless provoked.
Eels have leathery skin, and a long fin down their back and up their belly.
Like other fish, eels get oxygen from the water by pumping water across their gills. Cobias are a large fish, very streamlined, with a flat head and heavy body. They are opportunistic feeders, often swimming near the sharks, scavenging off of the shark's leftovers. Tarpon are a primitive fish, with a simple body shape and structure. They are silvery in color, with large silver scales.
