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. [1] [ needs update ]

This family contains the following genera: [2] [3]

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.

<i>Clibanarius</i> Genus of crustaceans

Clibanarius is a genus of hermit crabs in the family Diogenidae. Like other hermit crabs, their abdomen is soft-shelled and sheltered in a gastropod shell. Typically marine like all their relatives, the genus includes C. fonticola, the only known hermit crab species that spends all its life in freshwater. The feeding rates of Clibanarius species change with temperature which, given their broad distributions, may have considerable consequences for the stability reef systems as sea temperatures rise in the future.

<i>Pagurus bernhardus</i> Species of crustacean

Pagurus bernhardus is the common marine hermit crab of Europe's Atlantic coasts. It is sometimes referred to as the common hermit crab or soldier crab. Its carapace reaches 3.5 centimetres (1.4 in) long, and is found in both rocky and sandy areas, from the Arctic waters of Iceland, Svalbard and Russia as far south as southern Portugal, but its range does not extend as far as the Mediterranean Sea. It can be found in pools on the upper shore and at the mean tide level down to a depth of approximately 140 metres (460 ft), with smaller specimens generally found in rock pools around the middle shore and lower shore regions, with larger individuals at depth. P. bernhardus is an omnivorous detritivore that opportunistically scavenges for carrion, and which can also filter feed when necessary.

<span class="mw-page-title-main">Diogenidae</span> Family of crustaceans

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.

<i>Pagurus</i> Genus of crustaceans

Pagurus is a genus of hermit crabs in the family Paguridae. Like other hermit crabs, their abdomen is not calcified and they use snail shells as protection. These marine decapod crustaceans are omnivorous, but mostly prey on small animals and scavenge carrion. Trigonocheirus and Pagurixus used to be considered subgenera of Pagurus, but the former is nowadays included in Orthopagurus, while the latter has been separated as a distinct genus.

<i>Calcinus</i> Genus of crustaceans

Calcinus is a genus of hermit crabs in the family Diogenidae, containing the following species:

<span class="mw-page-title-main">Parapaguridae</span> Family of crustaceans

The Parapaguridae are a family of marine hermit crabs from deep waters. Instead of carrying empty gastropod shells like other hermit crabs, they carry colonies of dozen or more sea anemones or zoanthids. Some genera, such as Bivalvopagurus and Tylaspis, do not inhabit shells. The following genera are included:

<i>Paguristes</i> Genus of crustaceans

Paguristes is a genus of hermit crab in the family Diogenidae. It includes the following species :

<span class="mw-page-title-main">Pylochelidae</span> Family of crustaceans

The Pylochelidae are a family of hermit crabs. Its members are commonly called the 'symmetrical hermit crabs'. They live in all the world's oceans, except the Arctic and the Antarctic, at depths of 2,000 m (6,600 ft). Due to their cryptic nature and relative scarcity, only around 60 specimens had been collected before 1987, when a monograph was published detailing a further 400.

<i>Diogenes</i> (crustacean) Genus of crustaceans

Diogenes is a genus of hermit crabs.

<i>Dardanus megistos</i> Species of crustacean

Dardanus megistos, the white-spotted hermit crab or spotted hermit crab, is a species of hermit crab belonging to the family Diogenidae.

<i>Ciliopagurus</i> Genus of crustaceans

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 obesus is a fossil species of hermit crab, described from Rupelian (Oligocene) sediments at Sint-Niklaas, Belgium.

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.

<i>Aniculus maximus</i> Species of crustacean

Aniculus maximus, the hairy yellow hermit crab or large hairy hermit crab, is an aquatic hermit crab of the family Diogenidae.

Pseudopaguristes is a genus of hermit crabs in the family Diogenidae.

Tylaspis is a genus of hermit crabs in the family Parapaguridae. Its only known species is Tylaspis anomala.

<i>Aniculus</i> Genus of crustacean

Aniculus is a genus of aquatic hermit crab of the family Diogenidae.

<span class="mw-page-title-main">Xylopaguridae</span> Family of hermit crab

Xylopaguridae are a family of hermit crabs of the order Decapoda. It was erected in 2016 to accommodate one new genus, Prexylopagurus, and three existing genera that had previously been placed in Paguridae. They occur in the Atlantic, Indian, and Pacific Oceans.
