They closely resemble the Pacific hermit crab (Coenobita compressus) in appearance and they both have a shortened aquatic development stage. They are light brown to pale brown in color. They have two dark ovals on the front of the head. Their eyestalks are long and are the same color as the body. Each claw has a dark stripe vertical stripe. They have dark brown granuals all over the legs. The abdomen is short and fat.

Seashell preference
The preferred seashells of C. variabilis include Babylonia, Nerita, Phasianella, Thais, Tonna and Turban seashells. They are also found to be fond of several varieties of land snail shells such as Aratan snail and rice snail.
