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 Caribbean hermit crab, also known as the soldier crab, West Atlantic crab, tree crab, or purple pincher, is a species of land hermit crab native to the west Atlantic, Belize, southern Florida, Venezuela, and the West Indies.
The Ecuadorian hermit crab also known as the Pacific hermit crab is a species of land hermit crab. It is one of the two land hermit crabs commonly sold in North America as pets, the other being the Caribbean hermit crab.
The Australian land hermit crab is a terrestrial hermit crab species, native to Australia. It is a nocturnal, omnivorous crustacean. They are gregarious and thrive in tropical areas near water.
The Coenobitidae are the family of terrestrial hermit crabs, widely known for their land-living habits as adults. They are found in coastal tropical regions around the world and require access to the ocean to breed.
The genus Coenobita contains 17 species of terrestrial hermit crabs. Several species in this genus are kept as pets.
Coenobita perlatus is a species of terrestrial hermit crab. It is known as the strawberry hermit crab because of its reddish-orange colours. It is a widespread scavenger across the Indo-Pacific, and wild-caught specimens are traded to hobby aquarists.
Coenobita cavipes 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.
Coenobita rugosus is a species of land hermit crab native to Indonesia, Australia and the east African coast to the south west Pacific.
Coenobita purpureus, known generally as the Okinawan blueberry hermit crab or blueberry hermit crab, is a species of land hermit crab in the family Coenobitidae. They are typically a blue/purple color with white eyestalks, a red antennae, and a brown antennae. They also have gastropod shells.
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.
Coenobita violascens is a species of land hermit crab from family Coenobitidae. It is native to the Indonesia, Nicobar Islands, Thailand, Cambodia, Philippines, and Tanzania.
A branchiostegal lung is a respiration organ used by some air-breathing arthropods. It is one of the most significant adaptations of some crabs and hermit crabs such as the coconut crab to their terrestrial habitats.
The coconut crab is a terrestrial species of giant hermit crab, and is also known as the robber crab or palm thief. It is the largest terrestrial arthropod known, with a weight of up to 4.1 kg (9 lb). The distance from the tip of one leg to the tip of another can be as wide as 1 m. It is found on islands across the Indian and Pacific Oceans, as far east as the Gambier Islands, Pitcairn Islands and Caroline Island and as far south as Zanzibar. While its range broadly shadows the distribution of the coconut palm, the coconut crab has been extirpated from most areas with a significant human population such as mainland Australia and Madagascar.
A number of lineages of crabs are designed to live predominantly on land. Examples of terrestrial crabs are found in the families Gecarcinidae and Gecarcinucidae, as well as in selected genera from other families, such as Sesarma, although the term "land crab" is often used to mean solely the family Gecarcinidae.
Coenobita scaevola is a species of terrestrial hermit crab from the western Indian Ocean and Red Sea.
Hungry Bay Nature Reserve is a nature reserve on the east coast of Bermuda. It was established in 1986. It is considered the best example of coastal mangrove swamp on the island. It includes the Hungry Bay area and the largest mangrove coastal swamp in Bermuda. It is protected by a Tree preservation order (T.P.O.) and designated as an official Nature Reserve within the Parks system of Bermuda.
