Summary

Calcinus latens is the widely-distributed hermit crab species found from beach rock to rubble crest. The body of C. latens is generally dark-green fading to white on the legs and abdomen, which is inserted to a gastropod shell. The distinct morphological feature of this species is the purple band on the walking legs. Hermit crabs are known to actively select shells by the size, shape and quality. In the field, shell availability is often limited and the competition with the difference in habitat between species as a result is observed. Hermit crabs are ecologically important as the hosts of parasites as well as the prey of fish and birds. The lifecycle of C. latens is biphasic with planktonic larvae; the breeding pattern peaking twice a year is likely to be the strategy to avoid competition with a sympatric species. The evolution of the genus suggests the strong dispersal ability of Calcinus species. The major threats to hermit crabs are the loss of coral habitat by climate change, ocean acidification, and exploitation for the ornamental use in the aquarium.
