![]() ![]() This is an ordinary activity increased by the presence of others (Wilson 1975). clypeatus uses “social facilitation as a foraging statagy” (Kurta 1982). The hermit crabs have a complex social structure. clypeatus is temporally separated from its competitors (Morrison 2006). The crabs bury themselves beneath leaves, rocks, or sand during the day to avoid desiccation (Hazlett 1966). In Bermuda these crabs once roamed all over the island but now they are only know to inhabit Hungry Bay a small bay on the south shore of the island (Hass 1950 Walker 1994).Ĭoenobita clypeatus is a slow moving nocturnal terrestrial hermit crab (Hazlett 1964 Hazlett 1966). clypeatus has been found to travel across many different habitats and have climbed mountains as high as 887 meters (Walker 1994). However their gills do not allow them to be fully submerged under water because the hermit crabs will drown. clypeatus has gills it must live in areas of high humidity. clypeatus spends most of its time in the woods but is known to travel to high sand hills near the shore (Sterrer 1986). Coenobita clypeatus is a tropical land hermit crab that lives throughout the Caribbean and as far north as Florida and Bermuda (Kurta 1982). Hermit crabs in the genus Ceonobita are found on tropical and subtropical islands in the Pacific, Atlantic and Indian Oceans (Chance and Hobbs 1969 Ball 1972 DeWiled 1973 Alexander 1979 Page and Willason 1982 Willason and 3). Coenobita animals are named so for their communal living (Fenner 1999). Order Decopoda is defined by three thoratic appendages and five pairs of walking legs. Organisms in the class Malacostraca have trunks with fourteen segments, eight on the thoracic, six on the abdomen. Crustaceans also have biramous appendages meaning they have two part appendages, each part performing a different function. Crustaceans have 5 paired head appendages, which include antennae, mandibles and two sets of maxilla. clypeatus population.Īrthropods have an articulated, segmented, chininous exoskeleton (Wood 2007). Unfortunately there are no Bermudian laws protecting the dwindling C. Recent research has pointed to shell availability as the determining factor in population size. The purple pincher hermit crab was said to be found every where on Bermuda, now it is only found in a single bay on the south shore. ![]() clypeatus population pales in comparison to the population of the 1950s. In 1994 their populations was estimated to be only 150 individuals. In Bermuda the purple pincher hermit crab has an extremely small population. While the purple pincher hermit crab is terrestrial it must return to the water to spawn and release it's larvae into the ocean. clypeatus is also cannibalistic and will eat vulnerable molting crabs. clypeatus is extremely social the species is known to be aggressive towards other hermit crabs in their group to steal better fitting shells. These creatures are extremely social, foraging and traveling in groups. Living in humid areas this terrestrial hermit crab is a nocturnal scavenger that uses a gastropod shell to protect its soft body parts.
