A fish found along the coasts from Hokkaido to Kyushu and in nearby seas. It swims by wriggling its long, slender body.
It looks like an eel, but you can tell it apart because its upper jaw sticks out past the lower jaw and its body has white dots.
It is active at night, coming out of its burrow after dark to eat crustaceans like shrimp and crabs, worms, shellfish and fish.
How the Whitespotted conger lives
It lives on sandy or muddy bottoms in shallow seas.
