Peripatopsis Capensis Leg Anatomy IMG 0783a
''Peripatopsis'' is a genus of South African velvet worms in the Peripatopsidae family. The number of legs in this genus ranges from as few as 16 pairs (e.g., in '' P. clavigera'') to as many as 25 pairs (in '' P. moseleyi'') and varies within species when the number is greater than 18 pairs. Velvet worms in this genus feature a last pair of legs (the genital pair) that is rudimentary or reduced in size, mainly in males. This genus exhibits matrotrophic viviparity, that is, mothers in this genus retain eggs in their uteri and supply nourishment to their embryos, but without any placenta. Species The genus ''Peripatopsis'' consists of the following species: * ''Peripatopsis alba'' Lawrence, 1931 — white cave velvet worm * '' Peripatopsis balfouri'' (Sedgwick, 1885) * '' Peripatopsis birgeri'' Ruhberg & Daniels, 2013 * '' Peripatopsis bolandi'' Daniels et al., 2013 * ''Peripatopsis capensis'' (Grube, 1866) * '' Peripatopsis cederbergiensis'' Daniels et al., 2013 * ''Peripatop ...

Peripatopsis Capensis
''Peripatopsis capensis'' is a species of velvet worm in the Peripatopsidae family. This species has 18 pairs of legs: 17 pregenital leg pairs with claws plus one strongly reduced last pair without claws or spinous pads. Females of this species range from 9 mm to 70 mm in length, whereas males range from 6 mm to 54 mm. The native range of this species is limited to the Cape Peninsula of South Africa. Introduced distribution Outside of its native range in South Africa, this species has also been found on Santa Cruz Island in the Galapagos Islands, thought to be an accidental human-mediated introduction. Santa Cruz Island also has one or more native species of velvet worms in the family 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 distribu ....

Peripatopsis Intermedia
''Peripatopsis intermedia'' is a species of velvet worm in the Peripatopsidae family. This species is about 33 mm long and has 19 pairs of legs: 18 pregenital leg pairs plus a last pair of much reduced legs. The type locality is in South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring count .... Although some authorities doubt the validity of this species and deem it to be a junior synonym of ''P. balfouri'', others consider these two to be separate species, citing the distance (168 km) between their type localities.

Onychophoran Genera
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 ...

Endemic Fauna Of South Africa
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peripatopsis Sedgwicki
''Peripatopsis sedgwicki'' is a species of velvet worm in the Peripatopsidae family. Also known as the Tsitsikamma velvet worm, this species has a narrow geographic distribution in South Africa but is especially abundant in the indigenous forest of the Tsitsikamma mountains. Recent phylogenetic analysis suggests that ''Peripatopsis sedgwicki'' is a species complex that contains three clades, each with a distinct geographic distribution, including at least one clade that may represent a novel species. Discovery This species was first described under the name ''Peripatus dewaali'' by the Dutch zoologist Max Weber in 1898 based on specimens he collected near the town on Knysna in the Western Cape province of South Africa. In 1899, the South African zoologist William F. Purcell provided a more detailed description of this species based on a male and eleven females that he found in 1896 in rotten wood in the forest and under heaps of weeds on farms near the town of Knysna. He named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
