Coenobitidae
The Coenobitidae are the family of terrestrial hermit crabs, widely known for their land-living habits as adults. They are found in coastal tropical The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to ... regions around the world and require access to the ocean to breed. Although coenobitids are fully terrestrial as adults, they spend their marine life as planktonic larvae. Female coenobitids return to the sea to hatch their eggs and their larvae develop through planktonic zoeal stages to a megalopa, in a similar way as the marine hermit crabs. Just like these species, after settlement, terrestrial hermit crabs megalopae recognize and co-opt gastropods shells, before migrating into the land and molting to the first crab stage. The 17 species are placed in two genera: References * Ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birgus Latro
The coconut crab (''Birgus latro'') is a species of terrestrial hermit crab, also known as the robber crab or palm thief. It is the largest terrestrial arthropod in the world, with a weight of up to . It can grow to up to in width from the tip of one leg to the tip of another. It is found on islands across the Indian Ocean, and parts of the Pacific Ocean as far east as the Gambier Islands, Pitcairn Islands and Caroline Island, similar to the distribution of the coconut palm; it has been extirpated from most areas with a significant human population, including mainland Australia and Madagascar. Coconut crabs also live off the coast of Africa near Zanzibar. The coconut crab is the only species of the genus ''Birgus'', and is related to the other terrestrial hermit crabs of the genus ''Coenobita''. It shows a number of adaptations to life on land. Juvenile coconut crabs use empty gastropod shells for protection like other hermit crabs, but the adults develop a tough exoskeleton ...

Coenobita Pseudorugosus
''Coenobita pseudorugosus'' is a species of terrestrial hermit crab, family Coenobitidae. Discovery First described in 1988, ''C. pseudorugosus'' is known to occupy the Philippines and Southwest Madagascar. As suggested by its name, this species closely resembles the morphology and behavior of the more common '' C. rugosus''. The very subtle differences may have delayed their identification as a distinct species. Morphology When first described, the adult (terrestrial, non- larval form) were noted to have shield length (i.e. the anterior-posterior length of the dorsal cephalothorax carapace) between 5.6 and 12.1 mm. Subsequent surveys described their shield length as anywhere between 5 mm to 30 mm, and body weight of 100 mg to about 25 g. They tend to be tan-brown in color, with dark brown stripes over the shield, and additional scattered dark colorations in ventral aspect of ocular peduncle as well as parts of second and third pereiopods (walking legs) ...

Coenobita Brevimanus
''Coenobita brevimanus'' is a species of terrestrial hermit crab belonging to the family Coenobitidae, which is composed of coastal living terrestrial hermit crabs. From there it belongs to the genus ''Coenobita'', one of two genera split from the family, which contains sixteen species. The Latin origins of the species name, ''brevimanus'', come from the adjective ''brevis'' ("small") and the noun ''manus'' ("hands"). It is known as the Indos crab or Indonesian crab because it is primarily distributed throughout the Indo-Pacific. Description ''C. brevimanus'' is one of the larger species in the genus ''Coenobita''. The adults can grow up to .5 pounds (230 g). They can live 12–70 years and are known to grow to the size of a coconut. During the beginning of the crab's juvenile stage the middle of its carapace possesses a long reddish pigment area as does each side wall of the carapace. As the crab reaches one month old these areas develop into a brown stripe down the middle of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermit Crabs
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless. The strong association between hermit crabs and their shelters has significantly influenced their biology. Almost 800 species carry mobile shelters (most often calcified snail shells); this protective mobility contributes to the diversity and multitude of crustaceans found in almost all marine environments. In most species, development involves metamorphosis from symmetric, free-swimming larvae to morphologically asymmetric, benthic-dwelling, shell-seeking crabs. Such physiological and behavioral extremes facilitate a transition to a sheltered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coenobita Scaevola
''Coenobita scaevola'' is a species of terrestrial hermit crab from the western Indian Ocean and Red Sea. Distribution ''Coenobita scaevola'' lives around parts of the Indian Ocean, including the Gulf of Aden and the coasts of Somalia and Pakistan. Although the hermit crabs of the Red Sea are poorly studied, they include ''C. scaevola'' as the region's only species of terrestrial hermit crab. Taxonomy ''Coenobita scaevola'' was first described in 1775 by Peter Forsskål, under the name ''Cancer scaevola'', with a type locality of Jeddah, Saudi Arabia. Life cycle Reproduction takes place during the hottest months of the year, when temperatures are . In common with other hermit crabs, the young animals of ''Coenobita scaevola'' pass through a number of larval phases, before reaching the glaucothoe and then the juvenile stage. ''C. scaevola'' has the greatest number of zoeal phases of any ''Coenobita'' species (seven), and they last longer than in any other ''Coenob ...

Coenobita Cavipes
''Coenobita cavipes'' (Passionfruit Hermit) is a species of land hermit crab native to the eastern parts of Africa, the Indonesia, Philippines, China, Japan, Malaysia, Taiwan, Polynesia, and Micronesia. While these hermit crabs are terrestrial, they prefer to reside near the shores for access of both water and land. ''C. cavipes'' usually uses empty turbo shells, and occasionally part of a hard passion fruit ''Passiflora edulis,'' commonly known as passion fruit, is a vine species of passion flower native to southern Brazil through Paraguay and northern Argentina. It is cultivated commercially in tropical and subtropical areas for its sweet, seedy .... Habitat and Ecology This land hermit crab lives in mangrove trees, are mainly nocturnal, and terrestrial species, however often prefer salt water inside of its shell. The larger hermit crabs have been known to submerge their entire bodies into the sea water. The saltwater is used to bind the shell to the crabs back throu ...

Coenobita Rubescens
''Coenobita rubescens'' is a species of terrestrial (land-living) hermit crab, family Coenobitidae. They are the only known terrestrial hermit crab species on the Atlantic coast of western Africa. They were first described by the German zoologist Richard Greeff in the West African islands of São Tomé and Rolas, after initially being misidentified as '' Coenobita rugosus''. They are able to venture far inland, in altitudes exceeding . In spite of this, the ovigerous females must release the fertilized eggs in the ocean for the larvae to develop (as with all known species of terrestrial hermit crabs). The species is presumably named for the dark red coloration of their exoskeleton. Under Greeff's original observation, this species has a more elongated antennule and the left cheliped lacks the stridulation ridges (as such seen in ''C. rugosus''), leading to the distinction. At approximately , they are rather small by ''Coenobita'' standards. As with other terrestrial hermi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
