Calcinus verrillii
''Calcinus verrillii'', commonly known as Verrill's hermit crab, is a species of hermit crab in the genus ''Calcinus'' which is endemic to Bermuda. It was first described by the American zoologist Mary J. Rathbun and named in honour of the American zoologist Addison Emery Verrill, who spent much time with his students studying the geology and marine fauna of Bermuda.
Although this hermit crab species generally inhabits the discarded shell of a free-living gastropod mollusc, it sometimes makes use of the empty, tube-like shells of certain gastropod mollusc species while the tube is permanently cemented to rocks in the reef.
==Description==
Like other crabs in the genus ''Calcinus'', ''C. verrillii'' has a robust, calcified carapace, eight thoracic segments and six or seven abdominal segments. The carapace and legs are spotted with purple and orange, the eyes have slender eyestalks and the front three pairs of walking legs are smooth and hairless. The soft abdomen is coiled and fits into the mollusc shell which the hermit crab uses for protection, the uropods at the tip of the abdomen gripping the inside of the shell.
