Red Flat Clawed Hermit Crab

Ar-1421 RED FLAT CLAWED HERMIT CRAB, Pagurus impressus

It’s claws are specially modified to inhabit fighting conch shells. They are an attractive, peaceful hermit found in deep water throughout the winter months.


They can range from a solid rust to a chocolate brown with alternating bands of light color with bright blue eye stalks. Their right cheliped is much larger than the left (Williams 1984).


Ranges from Diamonds Shoals, N.C to Pensacola, FL. Found on sandy bottoms, grassy flats or pilings and sometimes in sponges (Williams 1984).
