Tawny Hermit Crab - Coenobita rugosus

Order: Decapoda
Infraorder: Anomura
Family: Coenobitidae
Genus: Coenobita
Species: C. rugosus

Coenobita rugosus (colloquially referred to as ruggie) is a species of land hermit crab native to Australia and the east African coast to the south west Pacific.

C. rugosus has four walking legs, a small pincer, a large pincer, and antennae. When threatened C. rugosus is able to make a 'chirping' sound by rubbing its large pincer against its shell as a stridatory aparatus.

C. rugosus vary in color depending on nutritional intake and common colors include green, brown and tan; but black, white, pink, and blue have also been observed. They can be differentiated from other species of land hermit crabs by the pronounced striations (stitch marks) on their large pincer. Coenobita compressus and Coenobita perlatus also possess these striations to a lesser extent but can easily be distinguished from C. rugosus by size and color; especially in the case of the C. perlatus which is a striking red color as an adult.

They can be 15mm in length and their eyestalks are sandy in color and may have a brown stripe on the bottom of them. The bottom pair of the second antena are light orange in color. Their big claw has 7 ridges on the upper part and there is usually hair on the inside of both claws. On the last pair of walking legs, on the second segment, it is flattened and the color is lighter. The abdomen is short and fat.

As with other species of land hermit crabs C. rugosus are scavengers and will consume plants, dead fish, fruit and other detritus.
