Ophidonais is a genus of annelids belonging to the family Naididae. [1]
The species of this genus are found in Eurasia and America. [1]
Species: [1]
The Amiiformes order of fish has only one extant species, the bowfin. These Amiiformes are found in the freshwater systems throughout North America and parts of southern Canada. They live in freshwater streams, rivers, and swamps. These bowfin fish are not on the endangered list. They have the ability to go to the surface to breathe if the water level is too low. The extinct species of the Amiiformes can be found fossilized in Asia and Europe, but the bowfin is the last living species in the order.
Physeter is a genus of toothed whales. There is only one living species in this genus: the sperm whale. Two fossil species are currently known that are placed in the same genus: Physeter antiquus from the Pliocene of France, and Physeter vetus from the Quaternary of Georgia.
The Lamniformes are an order of sharks commonly known as mackerel sharks. It includes some of the most familiar species of sharks, such as the great white, as well as more unusual representatives, such as the goblin shark and megamouth shark.
Mesoplodont whales are 15 species of toothed whale in the genus Mesoplodon, making it the largest genus in the cetacean order. Two species were described as recently as 1991 and 2002, and marine biologists predict the discovery of more species in the future. They are the most poorly known group of large mammals. The generic name "mesoplodon" comes from the Greek meso- (middle) - hopla (arms) - odon (teeth), and may be translated as 'armed with a tooth in the centre of the jaw'.
Gervais's beaked whale, sometimes known as the Antillean beaked whale, Gulf Stream beaked whale, or European beaked whale is the most frequently stranding type of mesoplodont whale off the coast of North America. It has also stranded off South America and Africa.
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands.
Oplosaurus was a genus of sauropod dinosaur from the Barremian-age Lower Cretaceous Wessex Formation of the Isle of Wight, England. It is known from a single tooth usually referred to the contemporaneous "wastebasket taxon" Pelorosaurus, although there is no solid evidence for this.
Squalodon is an extinct genus of whales of the Oligocene and Miocene epochs, belonging to the family Squalodontidae. Named by Jean-Pierre Sylvestre de Grateloup in 1840, it was originally believed to be an iguanodontid dinosaur but has since been reclassified. The name Squalodon comes from Squalus, a genus of shark. As a result, its name means "shark tooth." Its closest modern relative is the South Asian river Dolphin.
Pristichampsus is a non-diagnostic genus of crocodylian from France and possibly also Kazakhstan that is part of the monotypic Pristichampsidae family. As the type species, P. rollianti, was based on insufficient material when described in 1831 and 1853, the taxonomic status of the genus is in doubt, and other species have been referred to other genera, primarily Boverisuchus.
Dermanura is a genus of leaf-nosed bats.
Saccolaimus is a genus of the bat family Emballonuridae, small insectivorous flying mammals with distinctive sheathtails and pouches at the wrist.
Ludiortyx is a bird genus from the Late Eocene. Its remains have been found in the Montmartre Formation at the Montmartre. A single species is accepted, Ludiortyx hoffmanni.
Stirlingia, commonly known as blueboy, is a genus of 7 species in the family Proteaceae, all of which are endemic to Western Australia.
Brachistosternus ehrenbergii is a scorpion species and the most cited species in the genus Brachistosternus. The species was first described by Paul Gervais in 1841. Its venom is toxic to mice.
Liocheles australasiae, the Dwarf Wood Scorpion, is a species of scorpion belonging to the family Hormuridae.
Metaperipatus is a genus of velvet worms in the family Peripatopsidae that contains the species Metaperipatus inae. The type locality is in central Chile.
Fredericella is a genus of bryozoans belonging to the family Fredericellidae.
