Abstract
The involvement of ground slope, waves and celestial cues in y‐axis orientation was studied for the striped hermit crab Clibanarius vittatus. This crab commonly lives subtidally along sheltered shorelines and displayed an escape response oriented in the offshore direction at the home beach. Laboratory studies indicated that crabs moved downslope at angles of 7° and greater. In a wave tank, they moved into approaching waves. As for celestial cues alone, crabs tested under clear skies in both the morning and afternoon displayed directional distributions significantly oriented in the same direction as crabs on the home beach. Crabs displayed random movements under cloudy skies. Thus, C. vittatus can use ground slope, waves and celestial cues for offshore orientation during its escape response.
