Sea animals and fish are frequently the victims of negative publicity. More often than not, browsing through wildlife documentary channels on television will reveal a disappointing trend. Many of the documentaries have names such as "Killer Squid" and "The Deadliest Octopus." No wonder some new divers are frightened by aquatic life!
Marine animal behavior can appear threatening to divers who do not understand the purpose behind the behavior. Many sea animals look threatening but are completely docile, and some animals that appear friendly can actually be quite aggressive.
Almost all aquatic life injuries to humans are caused by defensive behavior on the part of the animal. As long as you don't try to pull eels out of their holes, poke the lobsters, or attempt to ride the stingrays, you should be just fine. Don't bother the fish and they won't bother you.
Learn about some of the animals that divers commonly fear and to discover which are dangerous and which are not.

Moray Eels - Not Dangerous

Moray eels are large, marine eels commonly found sheltering under ledges or inside holes in the reef. New divers may find eels frightening because they have visible sharp teeth and because they hang around with their mouths open as if they are about to bite. This behavior, which may look like an eel is threatening divers, is really just a way for the eel to pump water across its gills to breathe. The only danger from eels is that they have terrible eyesight and may mistake a prodding finger or dangling piece of gear for a fish. Give moray eels space and they pose no threat.
