Moray Eels Facts and Photos

You can find moray eels in most saltwater marine environments. Even so, they also inhabit many freshwater systems and some brackish waters.

In general, you can consider morays as being the largest of all eel species – the most common being the ‘cosmopolitan eel’.

The moray eel classification is not listed as an endangered species. Even so, fishing for them ‘commercially’ does not take place in many countries.

Moray Eel Habitat

Morays tend to thrive better in shallow, warm water habitats. They live near the seabed of coral reef formations or spend their time hidden in rock crevices and small caves.

Muraenidae are carnivores. The giant moray is the biggest eel of the species. It will feed on almost all mollusks, squid, crabs, octopus, and cuttlefish. They also eat small tropical fishes, such as the damselfish species.

Moray eels often kill their prey either by wrapping their body around the victim. They will squeeze it until it gets crushed flat enough to swallow.

If not, they will tear their prey into small, bite-size pieces using two sets of razor sharp teeth. The back row of extra teeth help to break up the food ready for digestion.

One of the most curious of all moray eel facts is that it has two circular breathing gills located behind its head. They jabber their huge jaws constantly to circulate water from their mouth towards their gills.

The saltwater eel species can be quite aggressive. But, based on personal experiences, they rarely attack people scuba diving near their territory.

Note: I have yet to see a giant moray eel attack anyone snorkeling at the surface.
