Weasels are mammals of the genus Mustela of the family Mustelidae. The genus Mustela includes the least weasels, polecats, stoats, ferrets, and European mink. Members of this genus are small, active predators, with long and slender bodies and short legs. The family Mustelidae, or mustelids, is often referred to as the "weasel family". In the UK, the term "weasel" usually refers to the smallest species, the least weasel (M. nivalis), the smallest carnivoran species.
In taxonomy, binomial nomenclature, also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name, a binomen, binominal name, or a scientific name; more informally it is also historically called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called binominal nomenclature, with an "n" before the "al" in "binominal", which is not a typographic error, meaning "two-name naming system".
Flounders are a group of flatfish species. They are demersal fish, found at the bottom of oceans around the world; some species will also enter estuaries.
The Skagerrak is a strait running between the Jutland peninsula of Denmark, the east coast of Norway and the west coast of Sweden, connecting the North Sea and the Kattegat sea.
The wheatears are passerine birds of the genus Oenanthe. They were formerly considered to be members of the thrush family, Turdidae, but are now more commonly placed in the flycatcher family, Muscicapidae. This is an Old World group, but the northern wheatear has established a foothold in eastern Canada and Greenland and in western Canada and Alaska.
Pipistrellus is a genus of bats in the family Vespertilionidae and subfamily Vespertilioninae. The name of the genus is derived from the Italian word pipistrello, meaning "bat".
Pleuronectidae, also known as righteye flounders, are a family of flounders. They are called "righteye flounders" because most species lie on the sea bottom on their left sides, with both eyes on their right sides. The Paralichthyidae are the opposite, with their eyes on the left side. A small number of species in Pleuronectidae can also have their eyes on the left side, notably the members of the genus Platichthys.
The witch, known in English by a variety of other common names including the witch flounder, pole flounder, craig fluke, Torbay sole, and grey sole, is a species of flatfish from the family Pleuronectidae. It occurs on both sides of the North Atlantic Ocean on muddy sea beds in quite deep water. In northern Europe it has some importance in fisheries as a food fish.
Rhamphinion is a genus of pterosaurs from the Sinemurian-mid Pliensbachian-age Lower Jurassic Kayenta Formation of northeastern Arizona, United States. The type species is R. jenkinsi.
Euplectes is a genus of passerine bird in the weaver family, Ploceidae, that contains the bishops and widowbirds. They are all native to Africa south of the Sahara. It is believed that all birds in the genus are probably polygynous.
The brushtail possums are the members of the genus Trichosurus in the Phalangeridae, a family of marsupials. They are native to Australia and some small nearby islands. Unique among marsupials, they have shifted the hypaxial muscles from the epipubic to the pelvis, much like in placental mammals, meaning that their breathing cycle is more similar to the latter than to that of other non-eutherian mammals. In general, they are more terrestrially oriented than other possums, and in some ways might parallel primates.
The southern red bishop or red bishop is a small passerine bird belonging to the bishop and widowbird genus Euplectes in the weaver family, the Ploceidae. It is common in wetlands and grassland in Africa south of the Equator. North of the Equator, it is replaced by the northern red bishop or orange bishop which was formerly regarded as a subspecies of this species.
The blackfin flounder is a flatfish of the family Pleuronectidae. It is a demersal fish that lives in temperate waters at depths of between 8 and 1,600 metres, though it is most commonly found between 15 and 800 metres. Its native habitat is the northern Pacific, from the Sea of Japan to the Strait of Tartary and southern Kuril Islands and out into the Bering Sea. It grows up to 52 centimetres (20 in) in length, and can weigh up to 1.5 kilograms (3.3 lb). Maximum reported lifespan is 23 years.
The rex sole is a flatfish of the family Pleuronectidae. Locally, it may also be known as a witch or threadfin sole. It is a demersal fish that lives in temperate waters on sand or mud bottoms at depths of up to 900 metres (3,000 ft), though it is most commonly found between 61 and 500 metres. Its native habitat is the northern Pacific, from Baja California in Mexico up the coasts of the United States, British Columbia and Alaska, across the Bering Sea to the coast of Russia and the Sea of Japan. It is slow-growing, reaching up to 60 centimetres (24 in) in length, and it can weigh up to 2.0 kilograms (4.4 lb). Maximum reported lifespan is 24 years.
The willowy flounder is a flatfish of the family Pleuronectidae. It is a demersal fish that lives on bottoms at depths of between 100 and 200 metres. Its native habitat is the temperate waters of the Western Pacific, from Southern Hokkaido in Japan to the Gulf of Bohai, the East China Sea and Taiwan. It can grow up to 30 centimetres (12 in) in length. It is sometimes classified in the monotypic genus Tanakius.
Symposiachrus is a genus of birds in the family Monarchidae. Most species are endemic to islands in Melanesia but the spectacled monarch is widely distributed and occurs in parts of Indonesia and western Australia. The genus was previously lumped together in the genus Monarcha.
Mahuidacursor is a genus of basal ornithopod dinosaur from the Santonian Bajo de la Carpa Formation of the Neuquén Basin in northern Patagonia, Argentina. The type and only species is M. lipanglef.
Lonchophylla orienticollina is a species of bat found in Colombia, Venezuela, and Ecuador.
Afrocygnus is an extinct genus of swan, which lived during the Late Miocene, and perhaps up to the Late Pliocene, in what is today North Africa. The only genus of swan known in Africa, aside from fragmentary Pleistocene remains found in East Africa and from occasional observations of vagrant European swans along the Mediterranean coast, it lived in what was during the Miocene a damp wetland spanning from Libya to Chad, alongside the Antracothere Libycosaurus and the early Homininae Sahelanthropus. The genus is considered as the sister taxon of the extant genus Cygnus. Fossils of the genus have been uncovered in the Sahabi Formation of Cyrenaica in Libya, and in the Toros-Menalla locality in the Djurab Desert of Northern Chad.
Paralitherizinosaurus is an extinct genus of therizinosaurid dinosaur from the Late Cretaceous Osoushinai Formation of Hokkaido, Japan. The genus contains a single species, P. japonicus, known from a partial right hand and cervical vertebra. Paralitherizinosaurus represents the youngest therizinosaur known from Japan.
