Ciliopagurus is a genus of hermit crabs, of the family Diogenidae, which are sometimes referred to as the "left-handed hermit crabs",{{ITIS|taxon=Ciliopagurus Forest, 1995 |id=660085 |accessdate=25 August 2010}} because in contrast to most other hermit crabs, the left chela (claw) is enlarged instead of the right. They are found in the Indo-Pacific region and in the eastern Atlantic Ocean.{{cite book |author=P. J. F.
