Peripatidae
Peripatidae is a family of velvet worms. The oldest putative representatives of the family herald from Burmese amber dated to the mid-Cretaceous, around 100 Ma, with representatives from Dominican and Baltic amber attesting to a broader distribution in the Palaeogene / Neogene; molecular variability suggests that the family's crown group may have arisen in the early Mesozoic. Description The Peripatidae exhibit a range of derivative features. They are longer, on average, than the Peripatopsidae and also have more leg pairs. The number of leg pairs in the Peripatidae range from 19 (in ''Typhloperipatus williamsoni'') to 43 (in ''Plicatoperipatus jamaicensis''). The gonopore is always between the penultimate leg pair. There are no oviparous species—the overwhelming majority are viviparous. The females of many viviparous species develop a placenta with which to provide the growing embryo with nutrients. Distribution The Peripatidae are restricted to the tropical and subtropical z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Onychophora
Onychophora (from grc, ονυχής, , "claws"; and , , "to carry"), commonly known as velvet worms (due to their velvety texture and somewhat wormlike appearance) or more ambiguously as peripatus (after the first described genus, '' Peripatus''), is a phylum of elongate, soft-bodied, many-legged panarthropods. In appearance they have variously been compared to worms with legs, caterpillars, and slugs. They prey upon other invertebrates, which they catch by ejecting an adhesive slime. Approximately 200 species of velvet worms have been described, although the true number of species is likely greater. The two extant families of velvet worms are Peripatidae and Peripatopsidae. They show a peculiar distribution, with the peripatids being predominantly equatorial and tropical, while the peripatopsids are all found south of the equator. It is the only phylum within Animalia that is wholly endemic to terrestrial environments, at least among extant members. Velvet worms are generally c ...

Eoperipatus
''Eoperipatus'' is a Southeast Asian genus of velvet worm in the family Peripatidae. The number of legs in this genus varies within species and ranges from 22 pairs (in '' E. butleri'') to 25 pairs (in '' E. horsti'' and '' E. weldoni''). Species The genus contains the following described species: * '' Eoperipatus butleri'' Evans, 1901 * '' Eoperipatus horsti'' Evans, 1901 * ''Eoperipatus totoro'' Oliveira et al., 2013 * '' Eoperipatus weldoni'' Evans, 1901 ''Eoperipatus sumatranus'' (Sedgwick, 1888) is considered a ''nomen dubium'' by Oliveira et al. 2012. First recorded in Vietnam, ''Eoperipatus'' has now been found distributed throughout South-East Asia. An undescribed species is known to occur in Thailand. In addition, unidentified onychophorans have also been observed in Borneo and in central Vietnam Vietnam or Viet Nam ( vi, Việt Nam, ), officially the Socialist Republic of Vietnam,., group="n" is a country in Southeast Asia, at the eastern edge of mainland ...

Peripatopsidae
Peripatopsidae is one of the two living velvet worm families. Description The Peripatopsidae exhibit relatively many characteristics that are perceived as original or "primitive" with respect to the Peripatidae. The number of leg pairs in this family range from as few as 13 (in ''Ooperipatellus nanus'') to as many as 29 (in ''Paraperipatus papuensis''). Behind or between the last leg pair is the genital opening (gonopore). Both oviparous and ovoviviparous, as well as genuinely viviparous, species exist, although the Peripatopsidae essentially lack a placenta. Distribution The distribution of the Peripatopsidae is circumaustral; in particular, they inhabit Australasia, South Africa and Chile. Genera The family contains the following genera: * '' Acanthokara'' Reid, 1996 * '' Aethrikos'' Reid, 1996 * '' Aktinothele'' Reid, 1996 * ''Anoplokaros'' Reid, 1996 * '' Austroperipatus'' Baehr, 1977 * '' Baeothele'' Reid, 1996 * ''Centrorumis'' Reid, 1996 * '' Cephalofovea'' Ruhberg et al ...

Peripatus
''Peripatus'' is a genus of velvet worms in the Peripatidae family. The name "peripatus" (unitalicised and uncapitalised) is also used to refer to the Onychophora as a whole, although this group comprises many other genera besides ''Peripatus''. The genus ''Peripatus'' is found in Central America, the Caribbean and northern South America. Species The genus contains the following species: * '' Peripatus basilensis'' Brues, 1935 – Haiti * '' Peripatus bouvieri'' Fuhrmann, 1913 – Colombia * '' Peripatus brolemanni'' Bouvier, 1899 – Venezuela * '' Peripatus danicus'' Bouvier, 1900 – Virgin Islands * '' Peripatus darlingtoni'' Brues, 1935 – Haiti * '' Peripatus dominicae'' Pollard, 1894 – Dominica * '' Peripatus evelinae'' (Marcus, 1937) – Brazil * '' Peripatus haitiensis'' Brues, 1913 – Haiti * '' Peripatus heloisae'' Carvalho, 1941 – Brazil * '' Peripatus juanensis'' Bouvier, 1900 – Puerto Rico * '' Peripatus juliformis'' Guilding, 1826 – Saint Vincent Is ...

Mongeperipatus
''Mongeperipatus'' is a genus of Central American velvet worms in the family Peripatidae. The species in this genus are notable for their giant size (with the largest specimens ranging from 18 cm to 22 cm in length) and for the degree of sexual dimorphism Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most ani ... that they exhibit in the number of legs: females have 37 to 41 pairs, several more than the males, which have only 32 to 34 pairs.

Typhloperipatus Williamsoni
''Typhloperipatus'' is a genus of velvet worm in the family Peripatidae, containing the sole species ''Typhloperipatus williamsoni''. It is the only species in the phylum found in South Asia. The species was discovered in northeastern India in 1911. Discovery The species name was after Noel Williamson, a political officer at Sadiya who was murdered in 1911 along with Dr. J.D. Gregorson. The murders led to an expedition in the Abor region by the British government in India. Stanley Wells Kemp, then an assistant superintendent at the Indian Museum at Calcutta was a zoologist attached to this expedition. Three specimens were found on 29 December 1911 near the gorge of the Dihang River near Rotung. Although the nearest known velvet worm species, from Malaya, are typically found in dead wood, these were found mainly under large stones near the roots of trees. Subsequently some more specimens were found at the mouth of the Sireng stream and another specimen was found when the 32nd Si ...
