Crab activity in a laboratory arena was videotaped for analysis, while field observations were supplemented with super 8 mm filming. An ethogram of 24 action patterns was compiled from these qualitative observations. Mating behavior and general activity in the natural habitat were described. All social and most individual action patterns were performed with the chelipeds. Social action patterns not involving chelae contact between participants were the Shield, Presentation, Vertical Wave, Spread, and Jerk. Social action patterns during which chelae contact occurred were the Shield Push, Presentation Push, Vertical Push, Spread Push, Spread Grasp, and Thrust. Individual action patterns using chelipeds were the Snap Back, Sternal Scrape, Chelae Scrape, Buccal Scrape, Bulldozing Dig, and Aufbaumreflex. Other individual action patterns were the Leg Scrape, Eye Wipe, Foam Bathing, Abdominal Flap, Leg Dig, Flattened, and Pause. Activity in the natural habitat was associated with burrow possession. Social action patterns are interpreted here as aggressive, while individual action patterns probably functioned in maintenance. Observations suggest pheromone mediation of mating.
