Stridulating Hermit Crab

Strigopagurus strigimanus

The Stridulating Hermit Crab is a tropical crustacean found in the Eastern Indian Ocean, specifically endemic to Australia. This species is part of the family Diogenidae and is known for its benthic lifestyle, inhabiting subtidal zones. Divers can encounter this crab at various depths, with most sightings occurring shallower than 40 meters, though it can be found at depths up to 110 meters. The Stridulating Hermit Crab is harmless to humans and does not have any significant human uses. Its conservation status has not been evaluated by the IUCN, CITES, or CMS. As a benthic creature, it is likely to be found on sandy or muddy bottoms, where it scavenges for food. Divers encountering this crab may notice its unique stridulating behavior, which involves producing sound by rubbing certain body parts together. This behavior can be an interesting aspect of observing this species in its natural habitat.
