Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish m .... The fish is named after its appearance due to having an extremely reduced "face". The mouth is located on the underside of the head. The sides of the head do not display any visible eyes. However, ''Typhlonus nasus'' does possess eyes, which can be seen deep beneath the skin in small-sized specimens. It also possess two pairs of large nostrils towards the front of the head above the mouth. The species has discernible gill covers on each side of the head and large deciduous scales.

Ipnops Meadi
''Ipnops meadi'', also known as the grideye fish, is a highly specialized species of Placodithyran abyssal fish found in the Clarion-Clipperton Zone of the Indo-Pacific Ocean. The species was named after Giles W. Mead of the Harvard Museum of Comparative Zoology, a biology professor at Harvard, deep sea explorer, and ichthyologist. History ''Ipnops'' were first discovered and named in 1878 by Dr. Albert Günther during the expedition of . ''Ipnops'' was originally classified as a broad species of abyssal flat-headed fish with either very small eyes or membranes covering their eyes. Due to recent scientific advancements and increased deep-sea expeditions, the ''Ipnops'' genus now divided into three species (''I.agassizi'', ''I.meadi'', ''I.murrayi'') based on geographic location. Most information on ''Ipnops'' species has been collected via deep-sea expeditions, the most prominent being HMS ''Challenger'' (1878), “Galathea”(1950–52), and “Okeanos” (2017). Since ''Ipnops' ...

Ipnops Agassizi
''Ipnops'' is a genus of deep-sea fish in the family Ipnopidae, which also includes the better-known tripodfish (''Bathypterois grallator''). ''Ipnops'' are small, slender fish that live close to the ocean floor in the bathyal and abyssal zones. The genus is notable for its unusual eyes. Species There are currently three recognized species in this genus: * '' Ipnops agassizii'' Garman, 1899 (grideye fish) * ''Ipnops meadi'' J. G. Nielsen, 1966 * '' Ipnops murrayi'' Günther, 1878 Distribution Specimens of ''I. murrayi'' and ''I. agassizi'' have been caught at depths of 1392–3475 m; ''I. murrayi'' occurs in the Atlantic Ocean while ''I. agassizi'' occurs in the Indo-Pacific region. ''I. meadi'' is also found in the Indo-Pacific, but occurs deeper at 3310–4970 m. Biology ''Ipnops'' has only recently been observed in the wild, so details of their life history has mostly been inferred from the characteristics of captured specimens.

Ipnopidae
The Ipnopidae (deepsea tripod fishes) are a family of fishes in the order Aulopiformes. They are small, slender fishes, with maximum length ranging from about . They are found in temperate and tropical deep waters of the Atlantic, Indian, and Pacific Oceans. A number of species, especially in the genus '' Bathypterois'', have elongated pectoral and pelvic fins. In the case of the tripodfish, ''Bathypterois grallator'', these fins are three times as long as the body — up to a meter in length — and are used for standing on the sea floor. Ipnopids either have tiny eyes, or very large eyes that lack any lens A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (''elements ...; in either case they have very poor vision and are unable to form an image.

Salmoniformes
Salmonidae is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes . It includes salmon (both Atlantic and Pacific species), trout (both ocean-going and landlocked), chars, freshwater whitefishes, graylings, taimens and lenoks, which are collectively known as the salmonids ("salmon-like fish"). The Atlantic salmon (''Salmo salar''), whose Latin name became that of its genus '' Salmo'', is also the source of the family and order names. Salmonids have a relatively primitive appearance among the teleost fish, with the pelvic fins being placed far back, and an adipose fin towards the rear of the back. They have slender bodies, with rounded scales and forked tails, and their mouths contain a single row of sharp teeth. Although the smallest species is just long as an adult, most are much larger, with the largest reaching . All salmonids spawn in fresh water of upper reaches of rivers and creeks, but in many cases, the fish spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anguilliformes
Eels are ray-finned fish belonging to the order Anguilliformes (), which consists of eight suborders, 19 families, 111 genera, and about 800 species. Eels undergo considerable development from the early larval stage to the eventual adult stage and are usually predators. The term "eel" is also used for some other eel-shaped fish, such as electric eels (genus ''Electrophorus''), spiny eels (family Mastacembelidae), swamp eels (family Synbranchidae), and deep-sea spiny eels (family Notacanthidae). However, these other clades evolved their eel-like shapes independently from the true eels. Eels live both in salt and fresh water, and some species are catadromous. Description Eels are elongated fish, ranging in length from in the one-jawed eel (''Monognathus ahlstromi'') to in the slender giant moray. Adults range in weight from to well over . They possess no pelvic fins, and many species also lack pectoral fins. The dorsal and anal fins are fused with the caudal fin, forming ...
