Body

Like other eels, Moray eels look something like a fish and something like a snake.

The body is generally patterned. In some species, the inside of the mouth is also patterned.

Moray eels normally have wide jaws and large sharp teeth, but some types of Moray eel have blunt teeth which help them to eat animals that live in shells. Morays also have pharyngeal jaws inside the main jaws.

Typically, moray eels grow to a length of about 1.5 metres. The largest known moray eel is the Slender giant moray, which can reach 4 metres in length. Moray eels live in coral reefs and rocky areas, at a depth of about 200m.

Habitat
Gymnothorax undulatus occupying a dead patch reef, located in Kona, Hawaii

The moray eel can be found in both freshwater habitats and saltwater habitats. However most live in the sea in salt water, never entering fresh water.

Echidna nebulosa

Moray eels normally live in warmer waters, but it depends on the type of eel.

Feeding behavior

Morays are opportunistic, carnivorous predators[2] and feed primarily on smaller fish, crabs, and octopuses.[3]

There are not many animals that eat eels, but groupers, barracudas and sea snakes do eat them.[4] Humans also eat eels.

Relationship with humans

Humans eat eels, but sometimes Moray eels will give people food poisoning. Moray eels are also caught to put in aquariums for people to look at. Some types of Moray eel may be considered beautiful and hard to find, in which case they will be expensive to buy.
