Acanthodactylus is a genus of lacertid lizards, commonly referred to as fringe-fingered lizards, fringe-toed lizards, and spiny-toed lizards.
The Tettigoniinae are a subfamily of bush crickets or katydids, which contains hundreds of species in about twelve tribes.
Procambarus is a genus of crayfish in the family Cambaridae, all native to North and Central America. It includes a number of troglobitic species, and the marbled crayfish (marmorkrebs), which is parthenogenetic. Originally described as a subgenus for four species, it now contains 161 species in 16 subgenera.
The thorny-headed worm family Polymorphidae contains endoparasites which as adults feed mainly in fish and aquatic birds. When this taxon was erected by Meyer in 1931, a subfamily Polymorphinae was established in it. As the Polymorphidae as presently understood would then be monotypic, with no basal genera outside the Polymorphinae, the proposed subfamily is redundant for the time being and therefore most modern treatments simply omit it. Polymorphus minutus is an economically significant parasite in goose and duck farming.
The Noronha skink is a species of skink from the island of Fernando de Noronha off northeastern Brazil. It is covered with dark and light spots on the upperparts and is usually about 7 to 10 cm in length. The tail is long and muscular, but breaks off easily. Very common throughout Fernando de Noronha, it is an opportunistic feeder, eating both insects and plant material, including nectar from the Erythrina velutina tree, as well as other material ranging from cookie crumbs to eggs of its own species. Introduced predators such as feral cats prey on it and several parasitic worms infect it.
Trachylepis tschudii is an enigmatic skink, purportedly from Peru. First described in 1845 on the basis of a single specimen, it may be the same as the Noronha skink (T. atlantica) from Fernando de Noronha, off northeastern Brazil. T. tschudii represents one of two doubtful records of the otherwise African genus Trachylepis on mainland South America; the other is T. maculata from Guyana.
Macrobrachium is a genus of freshwater prawns or shrimps characterised by the extreme enlargement of the second pair of pereiopods, at least in the male.
Tubiluchidae is one of the two families of priapulimorphidan priapulid worms.
Berlandina is a genus of ground spiders that was first described by R. de Dalmas in 1922.
Demotina is a genus of leaf beetles in the subfamily Eumolpinae. There are over 50 described species in Demotina. The genus is native to Asia, Australia and Oceania, though one species is an adventive species in the southeastern United States in North America. Some species are known to be parthenogenetic.
Nectonema is a genus of marine horsehair worms first described by Addison E. Verrill in 1879. It is the only genus in the family Nectonematidae described by Henry B. Ward in 1892, in the order Nectonematoidea, and in the class Nectonematoida. The genus contains five species; all species have a parasitic larval stage inhabiting crustacean hosts and a free-living adult stage that swims in open water.
Chordodidae is a family of parasitic horsehair worms belonging to the order Gordioidea; its taxonomy is under review.
Spinochordodes is a genus of worms belonging to the family Chordodidae.
Parachordodes is a genus of worms belonging to the family Chordodidae.
Paragordionus is a genus of worms belonging to the family Chordodidae.
Paragordius is a genus of worms belonging to the family Chordodidae. It was independently described by both Lorenzo Camerano in 1897 and Thomas Harrison Montgomery Jr. in 1898, though both authors gave the genus the same name.
Neochordodes is a genus of worms belonging to the family Chordodidae.
Acutogordius is a genus of worms belonging to the family Gordiidae.
Pseudochordodes is a genus of worms belonging to the family Chordodidae.
Oregodasys is a genus of worms belonging to the family Thaumastodermatidae.
