Paralithodes platypus, commonly known as the is a species of large, commercially valuable crab found in the North Pacific Ocean. This species exhibits distinct characteristics and plays a significant role in its marine environment.
Description & Characteristics
The is a striking crab characterized by its massive, spiny carapace. The carapace, which is the hard outer shell covering the crab’s body, can reach up to 20 cm in width. Paralithodes platypus possesses ten legs, including two prominent, large claws used for feeding and defense. The legs are covered in thick, spiny hairs, adding to the crab’s imposing appearance.

Habitat and Occurrence
Paralithodes platypus primarily inhabits the cold, deep waters of the North Pacific Ocean. The species has a depth range between 50 and 1,000 meters, with most individuals occurring in the bathyal zone – the deep-sea zone extending from 200 to 3,000 meters. The is commonly found in rocky, bottom environments with plentiful food sources. Its distribution spans from the Aleutian Islands in Alaska to the waters off Japan and Russia. Paralithodes platypus is a prevalent presence in these aquatic ecosystems, contributing to the biodiversity and food web of the region.
