Porcellanopagurus edwardsi is a species of hermit crab that lives in the waters around New Zealand and its subantarctic islands.
Distribution
[edit]Porcellanopagurus edwardsi is found around the Auckland Islands, Campbell Islands, Snares Islands, Stewart Island and along the coast of New Zealand's South Island. The closely related species P. filholi has a more northerly distribution, overlapping with that of P. edwardsi only in the region of the Banks Peninsula.[1]
Taxonomy
[edit]Porcellanopagurus edwardsi was described by Henri Filhol in 1885 as the only species in a new genus Porcellanopagurus; 12 further species have since been described.[2]
Description
[edit]Unlike most hermit crabs, Porcellanopagurus edwardsi is almost symmetrical, but its abdomen is bent back over the carapace, so that the pleopods are dorsally situated. The abdomen is "grossly distorted",[3] and is usually covered by the shell of a bivalve or limpet, in contrast to the gastropod shell used by most hermit crabs.[1] The cephalothorax is flattened and extends outwards in a number of lobes, the largest of which is the rostrum at the front of the animal.[4]
