Geographic range
The chain moray eel inhabits the tropical and subtropical waters of the western Atlantic Ocean, from
Florida, the Bahamas and the Gulf of Mexico to the Caribbean, then along the coasts of Central and South America as far south as Brazil. It is also widely distributed around the many islands of the West Indies, including
Guadeloupe, where it is one of the commonly encountered moray eel species.
Habitat
The chain moray eel is found in shallow tropical waters, generally from the surface down to depths of around 33 feet. It shelters in crevices within coral reefs and rocky structures. With its body hidden deep inside its refuge, you will often only see its head protruding from the opening as it watches its surroundings.
Diet
The chain moray eel feeds mainly on small fish, but also on invertebrates such as squid, shrimp and crabs.
Reproduction
Because of its nocturnal lifestyle, the reproduction of the chain moray eel is still poorly understood. The female lays eggs that hatch into small, flattened, transparent larvae.
