The Japanese Spider Crab is a large species of deep-sea crab found in both Endless Ocean and Endless Ocean: Blue World.

Encyclopedia Description

Endless Ocean

“These large creatures have shell-covered bodies with ten long, skinny legs. They have bright red backs and white bellies with speckled yellow patterns. This creature prefers to live in relatively deep places and can usually be found there year-round.

These animals have one set of pincered legs that are especially large in males. They are usually found in the sandy areas of the deep sea (they have been found up to 1,000 feet below the surface) but prefer to lay their eggs in shallow water.

These are the world’s largest crustaceans. Their shells, which are shed as they grow, can be up to 15 inches long, but it’s the leg span that is truly impressive. In 1921, there were unconfirmed reports of a specimen that was almost 20 feet across.”

Endless Ocean: Blue World

"This is the largest crustacean in the world, with a carapace measuring approximately 16 in. It has 10 long spindly legs with claws at the end of one pair, which grow especially large and long for males. Old records state that the biggest ever specimen was 19 ft."


Endless Ocean

In the first game, several can be found day and night in the Secret Cave in the Abyss and one can be found around Deep Valley.

Endless Ocean: Blue World

In the second game, two of these can be found in the Subterranean Reception Room in the Cavern of the Gods.


They normally stay in one place but move around a bit. When poked, they raise their front arms.
