Ooperipatellus Nickmayeri
''Ooperipatellus nickmayeri'' is a species of oviparous velvet worm in the family Peripatopsidae. This species is larger than any other in its genus (exceeding 60 mm in females; 30 mm in males); they can be more than twice as long as other ''Ooperipatellus'' species. These velvet worms have 14 pairs of legs, with the last pair reduced in size. This species varies in color from blue to predominantly orange-brown, with a light blue ventral surface. They are found in rotting logs and leaf litter.

Oviparous
Oviparous animals are animals that lay their eggs, with little or no other embryonic development within the mother. This is the reproductive method of most fish, amphibians, most reptiles, and all pterosaurs, dinosaurs (including birds), and monotremes. In traditional usage, most insects (one being ''Culex pipiens'', or the common house mosquito), molluscs, and arachnids are also described as oviparous. Modes of reproduction The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. However, the biologist Thierry Lodé recently divided the traditional category of oviparous reproduction into two modes that he named ovuliparity and (true) oviparity respectively. He distinguished the ... [...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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

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 ...

Ooperipatellus
''Ooperipatellus'' is a genus of Australian and New Zealand velvet worms in the Peripatopsidae family. Species in this genus are oviparous. Most species in this genus have 14 pairs of legs, but '' O. nanus'' has only 13 pairs, which is the minimum number found in the phylum Onychophora. Velvet worms in this genus are among the smallest known, with adults often only 10 to 20 millimeters long. Morphological and molecular data indicate that this genus is a monophyletic group. Species The genus contains the following species: * '' Ooperipatellus decoratus'' (Baehr, 1977) * '' Ooperipatellus duwilensis'' Reid, 1996 * '' Ooperipatellus insignis'' ( Dendy, 1890) * ''Ooperipatellus nanus'' Ruhberg, 1985 * '' Ooperipatellus nickmayeri'' Oliveira & Mayer, 2017 * '' Ooperipatellus parvus'' Reid, 1996 * '' Ooperipatellus spenceri'' Cockerell, 1913 * '' Ooperipatellus viridimaculatus'' (Dendy, 1900) ''Ooperipatellus cryptus'' Jackson & Taylor, 1994 is considered a ''nomen dubium In bin ...
