Abstract: The submersible ROV of the Monterey Bay Aquarium Research Institute provided video footage of crab-anemone interactions and was used to document a symbiotic relationship. Chorillia longipes, and Corallimorphus appear to inhabit a common depth range and pattern of distribution in the Monterey Canyon, and 81% of the corallipmorphs veiwed were hosts to crabs. Chorillia longipes were found between 298 meters and 650 meters, and the corallimorph was seen between the depths of 306 meters and 506 meters. The corallimorph appeared in highest concentration at North Wall and were virtually absent south of Point Joe. Video observations suggest that corallimorph reproduces both asexually and sexually. The crab gains food and possible protection from their host anemones, and thus the relationship may be best described as commensalism.
