Preliminary note on the ecology of Calcinus verrilli, an endemic Bermuda hermit crab occupying attached vermetid shells

Authors


Abstract

Calcinus verrilli (Rathbun), evidently the only species of hermit crab endemic to Bermuda, frequently occupies vermetid gastropod shells which are cemented fast to offshore reefs and the bottoms of shallow tidepools. This choice of shells poses several interesting ecological problems for the hermit crabs.
