The Pylochelidae are a family of hermit crabs. Its members are commonly called the ‘symmetrical hermit crabs’. They live in all the world’s oceans except the Arctic and the Antarctic at depths of 2000 m (6600 ft). Due to their cryptic nature and relative scarcity only around 60 specimens had been collected before 1987 when a monograph was published detailing a further 400.
