Homing in the mangrove swimming crab Thalamita crenata (Decapoda: Portunidae)

A field study on the Kenyan coast was designed to analyse this crab's ability to find its shelter after being moved away from it. In all the trials the direction chosen by the crabs were still clustered around the home direction and homing success was again high. Results support the hypothesis that T. crenata organizes some visual cues in a map-like arrangement and, detecting these cues from any release point within its home range, uses this map to return home.link_to_subscribed_fulltex
