The European eel is a species of eel. Their life history was a mystery for thousands of years, and mating in the wild has not yet been observed. The five stages of their development were originally thought to be different species. They are critically endangered due to hydroelectric dams, overfishing by fisheries on coasts for human consumption, and parasites.
The American eel is a facultative catadromous fish found on the eastern coast of North America. Freshwater eels are fish belonging to the elopomorph superorder, a group of phylogenetically ancient teleosts. The American eel has a slender, supple, snake-like body that is covered with a mucus layer, which makes the eel appear to be naked and slimy despite the presence of minute scales. A long dorsal fin runs from the middle of the back and is continuous with a similar ventral fin. Pelvic fins are absent, and relatively small pectoral fins can be found near the midline, followed by the head and gill covers. Variations exist in coloration, from olive green, brown shading to greenish-yellow and light gray or white on the belly. Eels from clear water are often lighter than those from dark, tannic acid streams.
Eels are any of several long, thin, bony fishes of the order Anguilliformes. They have a catadromous life cycle, that is: at different stages of development migrating between inland waterways and the deep ocean. Because fishermen never caught anything they recognized as young eels, the life cycle of the eel was long a mystery. Of particular interest has been the search for the spawning grounds for the various species of eels, and identifying the population impacts of different stages of the life cycle.
Moray eels, or Muraenidae, are a family of eels whose members are found worldwide. There are approximately 200 species in 15 genera which are almost exclusively marine, but several species are regularly seen in brackish water, and a few are found in fresh water.
Eels is an American rock band formed in Los Angeles in 1991 by singer-songwriter and multi-instrumentalist Mark Oliver Everett, known by the stage name E. Band members have changed over the years, both in the studio and on stage, making Everett the only official member for most of the band's work. Eels' music is often filled with themes of family, death, and unrequited love. Since 1996, Eels has released fifteen studio albums, seven of which entered the Billboard 200.
The Parramatta Eels are an Australian professional rugby league football club based in the Sydney suburb of Parramatta that competes in the National Rugby League (NRL).
Microtus is a genus of voles found in North America, Europe and northern Asia. The genus name refers to the small ears of these animals. They are stout rodents with short ears, legs and tails. They eat green vegetation such as grasses and sedges in summer, and grains, seeds, root and bark at other times. The genus is also called "meadow voles".
The singing vole, is a medium-sized vole found in northwestern North America, including Alaska and northwestern Canada.
Tetraodon is a genus in the pufferfish family (Tetraodontidae) found in freshwater in Africa. It is the type genus of the family and historically included numerous other species; several Asian species were moved to the genera Dichotomyctere, Leiodon and Pao in 2013.
Ophichthidae is a family of fish in the order Anguilliformes, commonly known as the snake eels. The term "Ophichthidae" comes from Greek ophis ("serpent") and ichthys ("fish"). Snake eels are also burrowing eels. They are named for their physical appearance, as they have long, cylindrical, snake-like bodies. This family is found worldwide in tropical to warm temperate waters. They inhabit a wide range of habitats, from coastal shallows and even rivers, to depths below 800 m (2,600 ft). Most species are bottom dwellers, hiding in mud or sand to capture their prey of crustaceans and small fish, but some are pelagic.
The Eel is an alias used by two fictional characters appearing in American comic books published by Marvel Comics. The first character to take up the identity was Leopold Stryke who first appeared in Strange Tales #112 created by Stan Lee and Dick Ayers, while his successor, Edward Lavell, first appeared in Power Man and Iron Fist #92. Both Eels were at one point members of the Serpent Squad even though the character they portray was not actually based on a snake, but on a fish that resembled a snake. Neither Eel has ever been featured as a regular character in any of Marvel's ongoing or limited series.
The Congo puffer or potato puffer is a freshwater pufferfish found in areas of the Congo River in Africa, including rapids.
Eels are ray-finned fish belonging to the order Anguilliformes, which consists of eight suborders, 20 families, 164 genera, and about 1000 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators.
Mastophorus muris is a parasitic nematode in the genus Mastophorus. It infects animals such as the marsh rice rat, hispid cotton rat, and singing vole.
The brindled madtom is a small catfish of the family Ictaluridae that is native to the eastern United States.
Eels are elongated fish, ranging in length from five centimetres (2 in) to four metres (13 ft). Adults range in weight from 30 grams to over 25 kilograms. They possess no pelvic fins, and many species also lack pectoral fins. The dorsal and anal fins are fused with the caudal or tail fin, forming a single ribbon running along much of the length of the animal. Most eels live in the shallow waters of the ocean and burrow into sand, mud, or amongst rocks. A majority of eel species are nocturnal and thus are rarely seen. Sometimes, they are seen living together in holes, or "eel pits". Some species of eels live in deeper water on the continental shelves and over the slopes deep as 4,000 metres (13,000 ft). Only members of the family Anguillidae regularly inhabit fresh water, but they too return to the sea to breed.
The electric eels are a genus, Electrophorus, of neotropical freshwater fish from South America in the family Gymnotidae. They are known for their ability to stun their prey by generating electricity, delivering shocks at up to 860 volts. Their electrical capabilities were first studied in 1775, contributing to the invention in 1800 of the electric battery.
