Lithogenes villosus is a species of armored catfish found in the Essequibo River drainage of the Potaro River in Guyana. [1]
The hairy woodpecker is a medium-sized woodpecker that is found over a large area of North America. It is approximately 250 mm (9.8 in) in length with a 380 mm (15 in) wingspan. With an estimated population in 2020 of almost nine million individuals, the hairy woodpecker is listed by the IUCN as a species of least concern. Some nomenclature authorities, such as the eBird/Clements checklist, place this species in the genus Dryobates.
The capelin or caplin is a small forage fish of the smelt family found in the North Atlantic, North Pacific and Arctic oceans. In summer, it grazes on dense swarms of plankton at the edge of the ice shelf. Larger capelin also eat a great deal of krill and other crustaceans. Among others, whales, seals, Atlantic cod, Atlantic mackerel, squid and seabirds prey on capelin, in particular during the spawning season while the capelin migrate south. Capelin spawn on sand and gravel bottoms or sandy beaches at the age of two to six years. When spawning on beaches, capelin have an extremely high post-spawning mortality rate which, for males, is close to 100%. Males reach 20 cm (8 in) in length, while females are up to 25.2 cm (10 in) long. They are olive-coloured dorsally, shading to silver on sides. Males have a translucent ridge on both sides of their bodies. The ventral aspects of the males iridesce reddish at the time of spawn.
Encephalartos is a genus of cycad native to Africa. Several species of Encephalartos are commonly referred to as bread trees, bread palms or kaffir bread, since a bread-like starchy food can be prepared from the centre of the stem. The genus name is derived from the Greek words en (within), kephalē (head), and artos (bread), referring to the use of the pith to make food. They are, in evolutionary terms, some of the most primitive living gymnosperms.
The Paraguaian hairy dwarf porcupine is a porcupine species from the family Erethizontidae. It is found in Argentina, Brazil, Paraguay and Uruguay.
The Hawaiian Lanternshark is a species of small squaliform shark in the family Etmopteridae.
Lithogenes is a genus of South American catfish of the family Loricariidae. It is the only genus within the subfamily Lithogeneinae.
Batrochoglanis is a small genus of catfishes of the family Pseudopimelodidae.
The tawny-breasted myiobius or tawny-breasted flycatcher is a species of passerine bird in the family Tityridae. It is found in Bolivia, Colombia, Ecuador, Panama, Peru, and Venezuela. Its natural habitat is subtropical or tropical moist montane forests.
Chrysospalax is a small genus of mammal in the family Chrysochloridae. The two members are endemic to South Africa. It contains the following species:
The bighairy armadillo is one of the largest and most numerous armadillos in South America. It lives from sea level to altitudes of up to 1,300 meters across the southern portion of South America, and can be found in grasslands, forests, and savannahs, and has even started claiming agricultural areas as its home. It is an accomplished digger and spends most of its time below ground. It makes both temporary and long-term burrows, depending on its food source. In Spanish it is colloquially known as "peludo".
Encephalartos villosus is a South African cycad occurring from the East London vicinity, where it is found near the coast, to the northern border of Eswatini (Swaziland) where it may grow as far as 100 km inland. The species is common throughout its range and is the most frequently cultivated in Southern Africa, largely because of its affordable price. As a result of its large geographical distribution, it is notably variable in leaf and cone shape.
Dikerogammarus villosus, also known as the killer shrimp, is a species of amphipod crustacean native to the Ponto-Caspian region of eastern Europe, but which has become invasive across the western part of the continent. In the areas it has invaded, it lives in a wide range of habitats and will prey on many other animals. It is fast-growing, reaching sexual maturity in 4–8 weeks. As it has moved through Europe, it threatens other species and has already displaced both native amphipods and previous invaders.
Sigaus villosus is New Zealand's largest grasshopper. It is only found in the central mountains of the South Island. The genus Sigaus is endemic to the New Zealand. Like all of New Zealand sub-alpine and alpine grasshoppers S. villosus has a 2 or 3 years life cycle. The eggs must ‘overwinter’ before they will hatch. Hoppers are found throughout the year and adult grasshoppers can be found throughout the New Zealand summer between December and April. Adult S. villosus do not overwinter.
Aegires villosus is a species of sea slugs. It is a dorid nudibranch, a shell-less marine gastropod mollusc in the family Aegiridae.
The microsporidian Cucumispora dikerogammari is a parasitic fungal species that infects the invasive amphipod Dikerogammarus villosus. The first recorded evidence of Cucumispora dikerogammari was, as cited by Ovcharenko and Vita, in Germany, circa 1895, by Dr. L. Pfeiffer in the Dnieper Estuary. The Dnieper Estuary and lower parts of the Danube River are considered to be the parasite’s native range. As its host, D. villosus, began to invade novel habitats, C. dikerogammari followed, and has now expanded its range to be found in many of the main bodies of water in Central and Western Europe. At this time, only limited research has been conducted regarding the ecological implications of C. dikerogammari spreading beyond its native range. However, there is evidence to suggest that C. dikerogammari may cause imbalance to the male/female sex ratio of its host D. villosus.
Anelaphus villosus, the twig pruner, is a species in the longhorn beetle family Cerambycidae. It is found in the eastern half of the United States and southeastern Canada.
Cistus × incanusL. is a hybrid between Cistus albidus and Cistus crispus. The name "Cistus incanus" has been used by other authors in a different sense, for Cistus creticus. The English name hoary rock-rose may refer to this species, among others.
The Iceland Sea is a small body of water delimited by the Jan Mayen fracture zone to the north, Greenland to the west, the Denmark Strait to the south, and the Jan Mayen Ridge to the east. Depths usually range from 500 to 2,000 meters but can be shallower on the Continental shelf of East Greenland. The Kolbeinsey Ridge crosses the Iceland Sea, dividing it into eastern and western parts.

Lithogenes wahari is a species of armored catfish found in Venezuela. This species reaches a length of 7.8 cm (3.1 in).
