Piluminid crabs
Family Pilumnidae
updated Dec 2019

Where seen? The most commonly seen member of this family on our shores are the Common hairy crabs (Pilumnus sp.) near rubble and reefs.

Features: Not all pilumnid crabs are hairy. They come in a wide variety of shapes and features and some are difficult to tell apart.

Status and threats: Several members of the Famil Pilumnidae are listed among the threatened animals of Singapore.
Like other creatures of the intertidal zone, they are affected by human activities such as reclamation and pollution. Trampling by careless visitors also have an impact on local populations.
