Moray Eels
by Krysta CardinaleMoray eels are considered large cosmopolitan eels, and have a snake-like appearance. They swim by flexing their whole body in a slithering like motion. Morays have the ability to tie and un-tie themselves into knots, which gives them leverage while fighting their live prey. There typical habitat consists of tropical and subtropical coral reefs. This is because they spend most of their time inside crevices and coves.
Many people make the mistake of putting Moray Eels into their aquariums and not knowing how to take care of them. All morays are aggressive dark water dwellers. They should be handled carefully, and the lights should not be kept too bright in the tank. These eels are carnivorous so they will eat other fish in the tank.
Physical Information on Moray Eels
Most morays grow to be a length of about five feet; however the slender giant moray can be as long as thirteen feet. This species have small circular gills on their flanks far posterior to the mouth. This is why it looks like morays have their mouths open all the time; it’s in order to breathe. They also secrete mucus over their skin, which has no scales. It serves as a defense in some types of morays by containing a toxin.
Morays have a dorsal fin right behind their heads. It is along their backs and joins with the caudal and anal fin. Many of the species lack a pelvic or a pectoral fin. They have very small eyes. Morays relay on their heightened sense of smell for hunting. Their diet consists mainly of fish, cephalopods, and crustaceans. Larger moray eels and Grouper fish are their only real predators.
Another feature that morays have is their patterned body. This pattern serves as a camouflage. It can also be found on the inside of their mouths since they keep their mouths open to breathe. Moray eels have wide jaws and large sharp teeth.
