Anotopterus vorax, the south ocean daggertooth, is a species of daggertooth. A. vorax inhabits the South Pacific, South Atlantic, South Indian Ocean, and Antarctic Ocean.
Deep-sea fish are animals that live in the darkness below the sunlit surface waters, that is below the epipelagic or photic zone of the sea. The lanternfish is, by far, the most common deep-sea fish. Other deep sea fishes include the flashlight fish, cookiecutter shark, bristlemouths, anglerfish, viperfish, and some species of eelpout.
Barracudinas are any member of the marine mesopelagic fish family Paralepididae: 50 or so extant species are found almost worldwide in deep waters. Several genera are known only from fossils dating back to the Ypresian epoch.
Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. The scientific name means "Aulopus-shaped", from Aulopus + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek aulós + Latin forma, the former in reference to the elongated shape of many aulopiforms.
Anotopterus nikparini is a species of fish in the family Anotopteridae, the daggertooths. It is native to the northern Pacific Ocean, where it occurs as far north as the Bering Sea and as far south as Japan and Baja California.
The daggertooth pike conger or the darkfin pike eel, is a species of eel in the pike conger family, Muraenesocidae. They primarily live on soft bottoms in marine and brackish waters down to a depth of 800 m (2,600 ft), but may enter freshwater. They are common to about 1.5 m (4.9 ft) in length, but may grow as long as 2.2 m (7.2 ft). Daggertooth pike congers occur in the Red Sea, on the coast of the northern Indian Ocean, and in the West Pacific from Indochina to Japan. It has also invaded the Mediterranean through the Suez Canal.
Dvinosaurs are one of several new clades of Temnospondyl amphibians named in the phylogenetic review of the group by Yates and Warren 2000. They represent a group of primitive semi-aquatic to completely aquatic amphibians, and are known from the Late Carboniferous to the Early Triassic, being most common in the Permian period. Their distinguishing characteristics are a reduction of the otic notch; the loss of a flange on the rear side of the pterygoid; and 28 or more presacral vertebrae.
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.
Boverisuchus is an extinct genus of planocraniid crocodyliforms known from the middle Eocene of Germany and western North America. It grew to approximately three metres (10 ft) in length.
The daggertooths are a genus of marine mesopelagic fish in the order Aulopiformes, the sole genus of the family Anotopteridae. They are found in oceans worldwide, but prefer cooler waters.
The daggertooth is a species of daggertooth. Its distribution includes the North Atlantic Ocean and west of Africa. The record size for this species is 96 cm and was hermaphroditic. Daggertooths are occasionally found dead in bottom trawls used for firefly squid or shrimp. They are similar to needlefish or gars. However, they are distinct. Netted daggertooth specimens are rarely identifiable, mostly because of their soft bodies, which are easily torn or flattened. This is typical of benthic animals of the deep ocean, like some transparent squids. In fact, the bodies are so soft, when pushed against the back of a trawl net, they often die because their organs are crushed and they rip. The habitat of the daggertooth is the open abyss, where few obstacles occur with which to come into physical contact.
Anotopterus sp. (2008) is a species of daggertooth discovered in the New Zealand Antarctic Ocean, at 71°S, and is one of the southernmost daggertooth specimens caught. Its golden luster and sapphire blue eyes are exquisite, but the colors fade quickly when the fish is removed from its habitat. The specimen found measured 50 cm and was only half grown. The fish paralyzes its prey by sinking its teeth into the flesh and then pulling backwards.
Acroplous is an extinct genus of dvinosaurian temnospondyl within the family Eobrachyopidae.
Colpodella is a genus of alveolates comprising 5 species, and two further possible species: They share all the synapomorphies of apicomplexans, but are free-living, rather than parasitic. Many members of this genus were previously assigned to a different genus - Spiromonas.
The voracious shrew is a common and widespread species of shrew native to China, India, Laos, Thailand, and Vietnam.
Acanthostomatops is an extinct genus of zatracheidid temnospondyl from the Lower Permian Döhlen Basin of Saxony.
Stagodontidae is an extinct family of carnivorous metatherian mammals that inhabited North America and Europe during the late Cretaceous, and possibly to the Eocene in South America.
Advancing Secondary Science Education through Tetrahymena is an organization at Cornell University that is dedicated to expanding the use of the protist Tetrahymena in K-12 classrooms. They are funded by the National Institutes of Health through the SEPA Program. Although their name includes the word "secondary," they have worked in recent years to develop materials for students in elementary, middle and high schools. The group develops modules, which are stand-alone labs or lessons that can be inserted into the curriculum of a class at the discretion of the teacher.
Laphria vorax is a species of robber flies in the family Asilidae.
Tachytrechus vorax is a species of long-legged fly in the family Dolichopodidae.
