Ptychognathus easteranus Rathbun

Easter Island Crab (Ptychognathus easteranus)

The Easter Island Crab, described in the year 1907, was originally thought to be restricted to the waters around Easter Island, but was later found to occur on other Polynesian islands as well.

The species is restricted to estuaries and shallow stagnant waters, for example tide pools, but regularly enters freshwater streams and thus, is mentioned here.
