Furry Hermit Crab

Paguristes ulreyi

The Furry Hermit Crab is a small crustacean belonging to the family Diogenidae, notable for its distinctive furry body. This unique feature aids in capturing detritus, which forms a significant part of its diet. Typically, these crabs are found in the Eastern Pacific, ranging from Canada to Mexico, inhabiting coastal waters. They are benthic creatures, residing at depths of up to 15 meters, often taking refuge in the discarded shells of snails such as Lithopoma gibberosum and Kelletia kelletii. Divers encountering the Furry Hermit Crab can expect to find them on rocky and soft bottoms. Their small size, reaching a maximum length of 2.5 cm, makes them a subtle presence on the ocean floor. Despite their small stature, they play an important role in the marine ecosystem as scavengers, contributing to the breakdown of organic matter. The reproductive behavior of these crabs involves a precopulatory courtship ritual, which is common in the order Decapoda. They utilize olfactory and tactile cues for mating, and sperm transfer is usually indirect. Currently, there is no evaluation of their conservation status by the IUCN.
