Russatus nigrescens is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Charopidae. This species is endemic to Micronesia.
The golden spiny mouse gets its name from the reddish-orange spiny fur that covers its body from head to tail. This coarse, inflexible fur is thought to protect it from predation. Aside from the golden fur that covers its head and upper parts, its flanks are yellow and its underside is pale. It has gray legs with pale feet and black soles. It is also described as having a small, but distinct white spot under each eye. It is often found in the wild missing a part or all of its tail because it is able to shed this as a defense mechanism. However, it is not known how this is done, how often it can occur, or under what conditions. It lives an average of three years in the wild. It is omnivorous and feeds on seeds, desert plants, snails, and insects. Living in desert regions, it is a xeric animal that obtains water from the plants that it eats and produces very concentrated urine in order to conserve water. A. russatus is naturally nocturnal, but adapts to being diurnal when it shares a habitat with A. cahirinus.
Euryoryzomys emmonsae, also known as Emmons' rice rat or Emmons' oryzomys, is a rodent from the Amazon rainforest of Brazil in the genus Euryoryzomys of the family Cricetidae. Initially misidentified as E. macconnelli or E. nitidus, it was formally described in 1998. A rainforest species, it may be scansorial, climbing but also spending time on the ground. It lives only in a limited area south of the Amazon River in the state of Pará, a distribution that is apparently unique among the muroid rodents of the region.
Euryoryzomys russatus, also known as the russet oryzomys, russet rice rat, or big-headed rice rat, is a species of rodent in the family Cricetidae. It is a member of the genus Euryoryzomys, which was split off from Oryzomys in 2006. It was first described by Johann Andreas Wagner in 1848. It is found in southern Brazil, eastern Paraguay and northeastern Argentina. It is considered a large species in its genus, with a reddish-brown coat, long tail length, and large skull. It is a terrestrial rodent, spending its time foraging for seeds, fruits, and insects. It is listed by the IUCN as least concern, although studies have shown it to be influenced by anthropogenic disturbances. Predators consist of small members of the order Carnivora.

The blackish antbird is a species of passerine bird in the family Thamnophilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, and Suriname. Its natural habitats are subtropical or tropical moist lowland forests, subtropical or tropical moist montane forests, and heavily degraded former forest.
The black pitohui is a species of bird in the monotypic genus of Melanorectes in the family Pachycephalidae. It is found throughout the highlands of New Guinea. Its natural habitat is subtropical or tropical moist lowland forests.
The ruddy tody-flycatcher is a species of bird in the family Tyrannidae.

The Himalayan shrew is a species of shrew in the subfamily Soricinae and tribe Nectogalini. It is found in Bhutan, China, India, Myanmar, and Nepal, and is the only extant species in the genus Soriculus.
The russet free-tailed bat is a species of bat in the family Molossidae. It is found in Cameroon, Democratic Republic of the Congo, Ghana, and Kenya. Its natural habitat is subtropical or tropical moist lowland forests.
The swift fruit bat is a species of megabat in the family Pteropodidae.
Russatus is a genus of small air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Charopidae.
Pacifastacus nigrescens, the sooty crayfish, is an extinct species of crayfish in the family Astacidae. It was originally described in 1857 by William Stimpson from the area around San Francisco, where it was once common in the creeks surrounding San Francisco Bay. The signal crayfish, Pacifastacus leniusculus was introduced to California, probably in the 19th century, and since then, no sightings of P. nigrescens have been made; it is now believed to be extinct. Intensive searches of its former habitat have found that every site where it once occurred is now occupied by either the signal crayfish or Procambarus clarkii.
Litsea nigrescens is a species of plant in the family Lauraceae. It is endemic to India.
The Eastern Cordillera small-footed shrew is a species of mammal in the family Soricidae. It is endemic to Colombia, where it is known from the western slopes of the central Cordillera Oriental at elevations from 1,300 to 2,715 m. It resembles C. colombiana. The species is only known from four individuals collected at two localities, the most recent record being from 1925.
The Colombian small-eared shrew is a species of mammal in the family Soricidae. It is endemic to Colombia, where it is known from the Cordillera Central in Antioquia Department at elevations from 1,750 to 2,800 m. It is found in montane forest and cultivated areas. It resembles C. brachyonyx.
