Meals

Brown fish feeding

This species is carnivorous and scavenger. During its active time it is hunting other fish and cephalopods. On some occasions it can be found hunting other moray fish. Their eyesight is not very good and, therefore, they base their hunting mainly on their smell. In this way they manage to track their prey.

It is a scavenger when it cannot find another type of food. This animal is situated as a predator in the highest part of the food chain. It is capable of eating other animals much larger than itself.

What makes the moray eel high on the food chain is that it is a large, vigorous predator. Your jaw has a highly developed system consisting of a second jaw that opens when the first is already open.

To feed, it grabs the prey with the first jaw and pulls out, fitting down the prey. These jaw adaptations make the moray eel a great biting machine. Most fish rely on opening their large jaws quickly causing the negative pressure of the water to suck prey into their mouths.

This is the ability of the eel to swallow fish and large creatures whole.
