Homeryon is a genus of blind, deep-sea crustaceans. It is named after the blind Greek poet Homer and the genus Eryon , which contains fossil relatives of the modern Polychelidae. It was separated from the genus Polycheles in 2001, and contains only two species. [2]
Homeryon armarium is only known to occur on the Kyushu–Palau Ridge (the ocean ridge between Japan and Palau) at depths between 520 and 700 metres (1,710 and 2,300 ft). It is listed as Data Deficient on the IUCN Red List. [4]
Only a single specimen of Homeryon asper (formerly Polycheles asper) has ever been collected. This type specimen was a juvenile female, with a carapace 32 millimetres (1.3 in) long, dredged up by the USS Albatross at a depth of 1,323–1,577 metres (4,341–5,174 ft) off Niʻihau in 1902. It is now housed in the National Museum of Natural History of the Smithsonian Institution. [2] H. asper is listed as Least Concern on the IUCN Red List. [5]
The Cape lobster, Homarinus capensis, is a species of small lobster that lives off the coast of South Africa, from Dassen Island to Haga Haga. Only a few dozen specimens are known, mostly regurgitated by reef-dwelling fish. It lives in rocky reefs, and is thought to lay large eggs that have a short larval phase, or that hatch directly as a juvenile. The species grows to a total length of 10 cm (3.9 in), and resembles a small European or American lobster; it was previously included in the same genus, Homarus, although it is not very closely related to those species, and is now considered to form a separate, monotypic genus – Homarinus. Its closest relatives are the genera Thymops and Thymopides.
Reef lobsters, Enoplometopus, are a genus of small lobsters that live on reefs in the Indo-Pacific, Caribbean and warmer parts of the Atlantic Ocean.
The family Polychelidae contains thirty-eight extant species of blind, benthic lobster-like crustaceans. They are found throughout the world's tropical, sub-tropical and temperate oceans, including the Mediterranean Sea and the Irish Sea.
Xenotyphlops is a genus of snakes, the only genus of the family Xenotyphlopidae, comprising two species found only in Madagascar. These snakes are also known as the Malagasy Blind Snake.
Xenotyphlops grandidieri is a species of blind snake endemic to Madagascar. No subspecies are currently recognized.
Madatyphlops cariei is an extinct blind snake species which was endemic to Mauritius. It is named for Paul Carié (1876–1930), an amateur naturalist attached to the Museum national d'Histoire naturelle, who made excavations in Mare aux Songes around 1900 where the remains of this species were discovered.
The gray flying fox is a species of flying fox in the family Pteropodidae. It is not to be confused with the grey flying fox. It is found in Indonesia, but not in the Philippines, despite occasional reference to such. Very little is known about this species. The gray flying fox has small size and neutral coloration with a brownish head and an orange abdomen. It probably roosts individually or in small groups. It was listed on appendix II of CITES, and is classified as "Data Deficient" by the IUCN. This species has been decimated by hunting for bushmeat in Indonesia. The hunters use fishing hooks, ropes, and other supplies to hunt the bats. The ropes and hooks are placed along their flight paths, tearing and ensnaring the bats' wings when are flying. In the course of a hunting season, entire colonies can be killed.
Allocrangonyx is a genus of troglobitic amphipod crustaceans from the South Central United States. The two species are both listed as vulnerable on the IUCN Red List. The animals are blind and unpigmented. During the male's development, the outer ramus of the third uropod differentiates into secondary segments and grows to a length greater than the animal's body length.
Platythelphusa is a genus of freshwater crabs endemic to Lake Tanganyika. It has been placed in a number of families, including a monotypic family, Platythelphusidae, as well as Potamidae and its current position in the Potamonautidae, and has also been treated as a subgenus of Potamonautes. It forms a monophyletic group, possibly nested within the genus Potamonautes, which would therefore be paraphyletic. The genus is the only evolutionary radiation of crabs to have occurred in a freshwater lake, and it occurred recently, probably since the Pliocene. This parallels the better known radiation of cichlid fishes in Lake Tanganyika. Only one other species of freshwater crab is found in Lake Tanganyika, Potamonautes platynotus.
The Viverrinae represent the largest subfamily within the Viverridae comprising five genera, which are subdivided into 22 species native to Africa and Southeast Asia. This subfamily was denominated and first described by John Edward Gray in 1864.
Trimeresurus gumprechti, known commonly as Gumprecht's green pitviper, is a species of venomous pitviper in the family Viperidae. The species is endemic to Asia.
Polycheles typhlops is a species of blind, deep water decapod crustacean with a cosmopolitan distribution. It is "one of the dominant and most characteristic crustaceans in deep-sea communities of the Mediterranean Sea".
Cardus crucifer is a species of blind deep-water decapod crustacean from the Atlantic Ocean, the only species in the genus Cardus. It differs from other members of the family Polychelidae in having only four pairs of claws, instead of five, in both sexes. The name Cardus refers to the thistle Carduus, in reference to the spiny thistle-like carapace. It is found in the eastern Atlantic from Portugal to Morocco and around the Azores and Canary Islands, and in the Bahamas, the Caribbean Sea and the Gulf of Mexico, at depths of 550–2,200 metres (1,800–7,220 ft).
Polycheles sculptus is a species of "strange, blind crustacean" resembling a prawn or a squat lobster. It has a cosmopolitan distribution in deep water, being found on both sides of the Atlantic Ocean, in the Mediterranean Sea, and across much of the Indo-West Pacific, at depths of 200–4,000 metres (660–13,120 ft).
Eunephrops manningi, the banded lobster, is a species of lobster found in the West Indies. It was named in 1974 by carcinologist Lipke Holthuis after his friend and fellow carcinologist Raymond B. Manning.
Mocquard's worm snake is a species of snake in the family Typhlopidae. The species is native to Africa.
Gierra's blind snake, also called an Usambara spotted blind snake, is a species of snake in the family Typhlopidae.
Brookesia therezieni, also known as the Perinet leaf chameleon, is a species of lizards in the family Chamaeleonidae. The species is endemic to eastern Madagascar. The International Union for Conservation of Nature (IUCN) classed the species as Least Concern. B. therezieni was initially described as a species new to science by Édouard-Raoul Brygoo and Charles Antoine Domergue in 1970.
Banc Capel is a guyot, or flat-topped underwater volcano, in the Coral Sea.
Polycheles suhmi, the blind lobster, is a species of crustacean resembling a prawn or a squat lobster. It was first described by Charles Spence Bate in 1878.
