The Japanese eel (Anguilla japonica; nihon unagi (日本鰻) [2]) is a species of anguillid eel found in Japan, Korea, Taiwan, China, and Vietnam, [3] as well as the northern Philippines. Like all the eels of the genus Anguilla and the family Anguillidae , it is catadromous , meaning it spawns in the sea but lives parts of its life in freshwater.
The California moray (Gymnothorax mordax) is a moray eel of the family Muraenidae, found in the eastern Pacific from just north of Santa Barbara to Santa Maria Bay in Baja California. [2] They are the only species of moray eel found off California, and one of the few examples of a subtropical moray.
Most eels live in the shallow waters of the ocean and burrow into sand, mud, or amongst rocks. A majority of eel species are nocturnal and thus are rarely seen. Sometimes, they are seen living together in holes, or "eel pits". Some species of eels live in deeper water on the continental shelves and over the slopes deep as 4,000 metres (13,000 ft).

The moray eel can be found in both fresh and saltwater habitats. The vast majority of species are strictly marine, never entering freshwater. Of the few species known to live in freshwater, the most well-known is Gymnothorax polyuranodon. [24] [25] Echidna nebulosa occupying a live coral reef, located in Sabang, Philippines

[23] [24] As open ocean voyagers, eels need the carrying capacity of the swimbladder (which makes up 3–6% of the eel's body weight) to cross the ocean on stored energy alone. Because the eels are catadromous (living in fresh water but spawning in the sea), dams and other river obstructions can block their ability to reach inland feeding grounds.
The young eel larvae live only in the ocean and consume small particles called marine snow. Anguillid eels lay adhesive demersal eggs (eggs that are free-floating or attached to substrate), and most species have no parental care. [29] Japanese eels (A. japonica) can lay between 2 million and 10 million eggs. [22]
