Macrobaenetes valgum, the Coachella giant sand treader cricket, is a species of insect in the family Rhaphidophoridae. It is endemic to the United States.
Genu valgum, commonly called "knock-knee", is a condition in which the knees angle in and touch each other when the legs are straightened. Individuals with severe valgus deformities are typically unable to touch their feet together while simultaneously straightening the legs. The term originates from the Latin genu, 'knee', and valgus which means "bent outwards", but is also used to describe the distal portion of the knee joint which bends outwards and thus the proximal portion seems to be bent inwards.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as only consisting of living members kept in captivity or as a naturalized population outside its historic range. Classification requires exhaustive surveys conducted within the species' known habitat with consideration given to seasonality, time of day, and life cycle. Once a species is classified as EW, the only way for it to be downgraded is through reintroduction.
The Daghestan pine vole is a species of rodent in the family Cricetidae. It is found in Russia, Georgia, Armenia, and Azerbaijan.
The Somali hedgehog is a species of mammal in the family Erinaceidae. It is endemic to Somalia and Somaliland. The Somali hedgehog is nocturnal.
The pale gray shrew is a species of mammal in the family Soricidae. It is endemic to Pakistan and is distributed in the Shigar valley and the western edge of Deosai.
Portenko's shrew is a species of mammal in the family Soricidae that is endemic to Russia.
The long-tailed brown-toothed shrew is a species of mammal in the family Soricidae. It is found in China, India, Myanmar, Nepal, and Vietnam.
The Lowe's shrew is a species of mammal in the family Soricidae. It is found in China, Myanmar, Thailand, and Vietnam.
Speleoperipatus is a monospecific genus of velvet worm in the Peripatidae family, containing the single species Speleoperipatus spelaeus. This species is a pale greenish yellow, almost white, with 22 or 23 pairs of legs and no eyes. Specimens range from 27 mm to 34 mm in length. The minimum number of leg pairs found in this species (22) is also the minimum number found in the neotropical Peripatidae. This velvet worm is viviparous, with mothers supplying nourishment to their embryos through a placenta.
Heteragrion is a genus of damselflies in the family Heteragrionidae.
Macrobaenetes kelsoensis is a species of insect in family Rhaphidophoridae known commonly as the Kelso giant sand treader cricket. It is endemic to California, where it is known only from San Bernardino County.
Macrobaenetes is a genus of sand-treader crickets in the family Rhaphidophoridae, found in California. There are at least four described species in Macrobaenetes.
Deltochilum valgum is a nocturnal, Neotropical species of dung beetle in the family Scarabaeidae, which has evolved a predatory lifestyle. While most other members of the true dung beetle subfamily feed on faeces or decomposing matter, D. valgum is highly specialised for eating millipedes; such a transition from scavenger to carnivore is rare. Whether this is novel adaption in this species or an ancestral adaption in the genus is unclear; at least two other species, Deltochilum kolbei and D. viridescens, which are not particularly closely related to D. valgum, also kill and feed on millipedes.
A vulnerable species is a species which has been categorized by the International Union for Conservation of Nature as being threatened with extinction unless the circumstances that are threatening its survival and reproduction improve.
Macrobaenetes algodonensis, the algodones sand treader cricket, is a species of camel cricket in the family Rhaphidophoridae. It is found in North America.
Endangered species, as classified by the International Union for Conservation of Nature (IUCN), are species which have been categorized as very likely to become extinct in their known native ranges in the near future. On the IUCN Red List, endangered is the second-most severe conservation status for wild populations in the IUCN's schema after critically endangered. In 2012, the IUCN Red List featured 3,079 animal and 2,655 plant species as endangered worldwide. The figures for 1998 were 1,102 and 1,197 respectively.
