About this guide
Hermit crabs are drawn to the smell of flesh from one of their own, Science News reports in “Hermit crabs are drawn to the dead.” In experiments on a beach in Costa Rica, land-dwelling hermit crabs swarmed plastic bottles containing crab flesh. The scent of the flesh signals the death of a hermit crab and thus is a cue that an empty shell — a limited resource for land-dwelling crabs — is available.
