Calcinus revi, commonly known as the white hermit crab, is a species of hermit crabs in the family Calcinidae. [1]
Calcinus revi reaches up to 1.5 cm (0.59 in) in length. Its body is purely white, antennae are yellow and the eyes appear to have a color combination of black and blue. [2]
The white hermit crab can be found in the Indo-West Pacific, including Hawaii, French Polynesia, South Pacific, [2] South Japan, and Mariana Islands. [3] [4]
This species of hermit crab can be found in the intertidal zone and shallow waters up to 6 m (20 ft) in depth.
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 halloween hermit crab, also known as the striped hermit crab or orange-legged hermit crab, is a brightly colored aquatic hermit crab of the family Diogenidae. Besides its ability to routinely clean algae in aquaria, the halloween hermit crab's festive striped coloration also appeals to enthusiasts; it is considered the most brightly colored hermit crab in normal aquarium use.
The Diogenidae are a family of hermit crabs, sometimes known as "left-handed hermit crabs" because in contrast to most other hermit crabs, its left chela (claw) is enlarged instead of the right. It comprises 429 extant species, and a further 46 extinct species, making it the second-largest family of marine hermit crabs, after the Paguridae.
The Paguridae are a family of hermit crabs of the order Decapoda. The king crabs, Lithodidae, are now widely understood to be derived from deep within the Paguridae, with some authors placing their ancestors within the genus Pagurus.
Calcinus is a genus of hermit crabs in the family Diogenidae, containing the following species:
Calcinus elegans, also known as the blue line hermit crab, is a small, tropical hermit crab.
Clibanarius fonticola is a species of hermit crab from Vanuatu. It lives exclusively in fresh water, the only hermit crab in the world to do so. While a number of other hermit crabs are terrestrial or live in estuarine habitats, and certain brackish water species can tolerate low salinity levels for a time, no other hermit crab spends its entire life in fresh water; the only other fully freshwater anomurans are the South American aeglids.
Ciliopagurus is a genus of hermit crabs, of the family Diogenidae, which are sometimes referred to as the "left-handed hermit crabs", because in contrast to most other hermit crabs, the left chela (claw) is enlarged instead of the right. They are found in the Indo-Pacific region and in the eastern Atlantic Ocean.
Ciliopagurus liui is a species of hermit crab native to the Gulf of Tonkin and waters to the south of Japan.
Ciliopagurus galzini is a species of hermit crab. It is one of four species in the "strigatus complex"; it resembles C. strigatus, with the most prominent difference being coloration. It is common in the shallow intertidal waters of the Tuamotus.
Ciliopagurus vakovako is a species of hermit crab native to the Marquesas Islands. It is typically found at a depth no lower than 57 metres (187 ft). C. vakovako appears to be a vicariant of C. strigatus, a species widespread throughout the Indo-pacific region.
Calcinus tubularis is a species of hermit crab. It is found in the Mediterranean Sea and around islands in the Atlantic Ocean, where it lives below the intertidal zone. Its carapace, eyestalks and claws are marked with numerous red spots. C. tubularis and its sister species, C. verrilli, are the only hermit crabs known to show sexual dimorphism in shell choice, with males using normal marine gastropod shells, while females use shells of gastropods in the family Vermetidae, which are attached to rocks or other hard substrates.
Aniculus maximus, the hairy yellow hermit crab or large hairy hermit crab, is an aquatic hermit crab of the family Diogenidae.
Calcinus verrillii, commonly known as Verrill's hermit crab, is a species of hermit crab in the genus Calcinus which is endemic to Bermuda. It was first described by the American zoologist Mary J. Rathbun and named in honour of the American zoologist Addison Emery Verrill, who spent much time with his students studying the geology and marine fauna of Bermuda.
Calcinus morgani, commonly known as Morgan's hermit crab, is a species of hermit crab in the family Diogenidae found in the Indo-West Pacific region, the type locality being Indonesia.
Aniculus hopperae, also known as reticulated Hawaiian hermit, is a species of hermit crab in the family Diogenidae from the Pacific Ocean. The specific name hopperae honors Carol N. Hopper from Waikīkī Aquarium.
Calcinus argus, also known as the Argus hermit crab, is a species of hermit crabs in the family Calcinidae described by David Wooster in 1984. Originating from the Indo-West Pacific near Hawaii.
Calcinus guamensis is a species of hermit crabs in the family Calcinidae.
Calcinus laurentae is a species of left-handed hermit crab in the family Diogenidae. The common name for Calcinus laurentae is Laurent's Hermit Crab or Redleg calcinus. Calcinus laurentae are native to Hawaii and the Hawaiian word for hermit crab is unauna.
Aniculus aniculus, the red hermit crab or scaly-legged hermit crab, is a species of aquatic hermit crab of the family Diogenidae. It is distributed across French Polynesia in the Gambier, Marquesas, Society, and Tuamotu archipelagoes. It has also been recorded in the Mozambique Channel and around Mauritius. Of the species in the genus Aniculus, only it and A. ursus are considered common. The species is the host of the parasitic isopod Parathelges aniculi, and it is one of several hermit crabs preyed upon by Nautilus macromphalus.
