Calcinus nitidus

Calcinus nitidus is a crustacean belonging to the family Diogenidae, commonly found in the Eastern Central Pacific, particularly in French Polynesia. This species inhabits shallow waters, typically at depths ranging from 0 to 10 meters, where it occupies benthic environments. Divers are likely to encounter this species in tropical regions, where it is part of the diverse marine ecosystem. The life cycle of Calcinus nitidus, like many decapods, involves a gonochoric reproduction system. Mating behavior includes a precopulatory courtship ritual, which relies on olfactory and tactile cues, and usually involves indirect sperm transfer. These behaviors are typical among members of the order Decapoda. There is no evaluation of its conservation status by the IUCN, CITES, or CMS.
