Pilumnoides inglei is a species of crab, known only from a few specimens collected on derelict boats on the south coast of England.
Pilumnoides inglei was described in 1987 during a revision of the genus Pilumnoides by Danièle Guinot and Enrique Macpherson. [1] [2] It was named after Ray W. Ingle, who worked at the Natural History Museum and wrote the important book British Crabs. [1] [3]
Although Pilumnoides inglei resembles P. perlatus very closely, the carapace and chelae (claws) of P. inglei are smoother than in P. perlatus. [1] The known adult specimens vary in size from 5.5 by 6.7 millimetres (0.22 in × 0.26 in) to 11.3 mm × 14.3 mm (0.44 in × 0.56 in). [1]
In 1900, Rupert Vallentin recorded specimens of Pilumnoides on a derelict ship in Falmouth harbour, Cornwall. [4] The ship was the 500-ton Liverpool barque Ruthen, carrying a consignment of guano from the Patagonian island of Lobos ( 45°4′1.5″S66°19′19.4″W / 45.067083°S 66.322056°W ), "about mid-way between Montividio [ Montevideo ] and the Straits of Magellan". [4] The ship was severely damaged in a gale off the Isles of Scilly, and was towed to Falmouth, where Vallentin found numerous Pilumnoides crabs among the dense seaweed on the ship's hull. Despite his attempts to introduce a new species to the area, by dispersing crabs about the harbour, the population did not persist. [4] Vallentin sent some of the specimens he had collected to Reginald Innes Pocock at the British Museum (now the Natural History Museum), who identified them as Pilumnoides perlatus. [4]
Further specimens were collected by G. W. Dock from the vessel Micfield at Plymouth in 1913. [1] Since 1913, no further specimens have been found. [5]
While the majority of Pilumnoides species occur around the Americas, Pilumnoides inglei is only known from a few specimens collected on the south coast of England. [1] Prior to 1987, specimens of Pilumnoides found in the British Isles had been identified as Pilumnoides perlatus , a species native to the Pacific coasts of South America. These specimens were thought to have been introduced by ships trading between South America and Europe. [1]
In their 1987 revision, Guinot and Macpherson separated the English specimens as a new species, and reappraised the hypotheses about its natural range. They concluded that the species had never been found in its natural habitat, but expected that the natural habitat would be located off the coast of England, and in the seas of northern Europe, rather than further afield. [1] Similarly, Guinot and Macpherson described the new species Pilumnoides rubus for specimens from South Africa, which were previously thought to be an introduced population of P. perlatus. [1]
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.
Maja brachydactyla is a species of crab in the family Majidae. It was initially described as a subspecies of M. squinado. A review of the species complex published in 1998 was able to differentiate between specimens from the Mediterranean Sea and those from the Atlantic Ocean, and concluded that the Atlantic specimens were a separate species, accepted as M. brachydactyla Balss, 1922.
Hemigrapsus crenulatus, the hairy-handed crab or papaka huruhuru, is a marine crab of the family Varunidae, endemic to the New Zealand coast, although a taxon in Chile may be conspecific. It is an intertidal species with semi-terrestrial tendencies. They are named by their characteristic setae, or patches of thick hair, on the chelipeds and legs. They can range from green to brown in coloration. Adult crabs are generally 2–4 cm (0.8–1.6 in) wide at the carapace, although the smallest mature crabs can be around just 1 cm (0.4 in) wide. and are able to survive and reproduce in environments of widely varying salinities.
Afrithelphusa is a genus of freshwater crabs in the family Deckeniidae. It contains four species, all of which were formerly listed as critically endangered by the International Union for Conservation of Nature (IUCN). They are all endemic to the Upper Guinean forests of Guinea and Sierra Leone.
Orithyia sinica, sometimes called tiger crab or the tiger face crab, is a "singularly unusual" species of crab, whose characteristics warrant its separation into a separate genus, family and even superfamily, having previously been included in the Dorippoidea or Leucosioidea. Its larvae, for instance, are unlike those of any other crab.
Pachygrapsus marmoratus is a species of crab, sometimes called the marbled rock crab or marbled crab, which lives in the Black Sea, the Mediterranean Sea and parts of the Atlantic Ocean. It is dark violet brown, with yellow marbling, and with a body up to 36 millimetres (1.4 in) long. A semiterrestrial omnivore, it feeds on algae and various animals including mussels and limpets.
Pseudozioidea is a superfamily of crabs, formerly treated in the Eriphioidea, Carpilioidea, Xanthoidea, Pilumnoidea and Goneplacoidea. A number of fossils from the Eocene onwards are known from the family Pseudoziidae. Eleven genera are recognised in three families:
Potamonautes sidneyi is a species of freshwater crab in the family Potamonautidae. The common name is the Natal river crab or Sidney's river crab, although they may also be referred to as "river crabs", "fresh water crabs" or "land crabs".
Maja capensis, the Agulhas spider crab, is a species of crab in the family Majidae.
Paraetisus globulus is a species of crab in the family Xanthidae, the only species in the genus Paraetisus. It was described in 1933 by Charles Melbourne Ward.
Around 65 species of crab occur in the waters of the British Isles. All are marine, with the exception of the introduced Chinese mitten crab, Eriocheir sinensis, which occurs in fresh and brackish water. They range in size from the deep-water species Paromola cuvieri, which can reach a claw span of 1.2 metres, to the pea crab, which is only 4 mm (0.16 in) wide and lives inside mussel shells.
Mictyris guinotae is a species of soldier crab of genus Mictyris, endemic to the Ryukyu Islands of Japan. They were named after Danièle Guinot, a professor at the Muséum national d'histoire naturelle in France, and were first treated as a separate species in a tribute volume to Guinot.
Pilumnoides is a genus of crabs in the family Pilumnoididae. The genus was erected by Hippolyte Lucas in 1844. It contains the following species:
Pilumnoididae is a family of crabs containing the genera Pilumnoides, with several species, and the monotypic Setozius.
Elinor Frances Vallentin (formerly Nichol; was a British botanist and botanical illustrator who made scientifically significant collections of botany specimens in the Falkland Islands. She co-authored the book Illustrations of the flowering plants and ferns of the Falkland Islands in 1921 with Enid Mary Cotton, a fellow botanist. This work was regarded as being particularly valuable because of Vallentin's botanical illustrations. The standard author abbreviation Vallentin is used to indicate this person as the author when citing a botanical name.
Neolithodes agassizii is a species of king crab native to the Western Atlantic. They live at depths of 200–1,900 metres (660–6,230 ft), and have been found as far south as Rio de Janeiro, as far north as latitude 36°, and near the Equator. It has been found in the southwestern Caribbean Sea as well as the Gulf of Mexico.
Neolithodes vinogradovi is a species of king crab whose native habitat ranges from the Arabian Sea to the Coral Sea.
Neolithodes asperrimus is a species of king crab native to the coast of Africa. It has been found in South Africa and Mauritania at depths of 997–1,862 metres (3,271–6,109 ft), and Neolithodes aff. asperrimus has been found in Madagascar, Réunion, and the South Region of Brazil.
Limnopilos is a genus of small hymenosomatid crabs endemic to Southeast Asia. The genus was described by Christina Chuang and Peter Ng in 1991, who identified the new species Limnopilos naiyanetri and distinguished it from the closely related genus Hymenicoides. Its true taxonomic classification was debated for several years, but in 2007 the discovery of a new species of crab in this genus solidified the distinction between Limnopilos and Hymenicoides. Many aspects of the genus Limnopilos are still poorly understood. Their ecology and natural history have not been studied in detail, and their reproductive cycle remains mysterious.
Gordonopsis is a genus of deep-sea porter crabs in the family Homolidae. The Homolidae are also known as carrier crabs or porter crabs for their fifth pereiopods, which they use to hold objects in place over the rear half of the carapace in a possible defence mechanism against predators. Species of Gordonopsis are found in deep waters of the Indo-West Pacific region. The genus was erected in 1995 by Danièle Guinot and Bertrand Richer de Forges.
