Opisthoproctidae
Barreleyes, also known as spook fish (a name also applied to several species of chimaera), are small deep-sea argentiniform fish comprising the family Opisthoproctidae found in tropical-to-temperate waters of the Atlantic, Pacific, and Indian Oceans. These fish are named because of their barrel-shaped, tubular eyes, which are generally directed upwards to detect the silhouettes of available prey; however, the fish are capable of directing their eyes forward, as well. The family name Opisthoproctidae is derived from the Greek words ''opisthe'' 'behind' and ''proktos'' 'anus'. Description The morphology of the Opisthoproctidae varies between three main forms: the stout, deep-bodied barreleyes of the genera ''Opisthoproctus'' and ''Macropinna'', the extremely slender and elongated spookfishes of the genera ''Dolichopteryx'' and ''Bathylychnops'', and the intermediate fusiform spookfishes of the genera ''Rhynchohyalus'' and '' Winteria''.

Opisthoproctus Soleatus
''Opisthoproctus soleatus'' is a species of fish in the family Opisthoproctidae. It was first described in 1888 by Léon Vaillant. The species lives in most tropical seas, but is more common in the eastern Atlantic, from western Ireland to Mauritania and from Sierra Leone to Angola, and also in the South China Sea. ''O. soleatus'' can grow to a standard length of and usually live from about deep. Description This species is a small fish, not exceeding in length. The body of ''Opisthoproctus soleatus'' is deep and laterally compressed. Scales are large, thin, and cycloid. The ventral side of the body was described by Vaillant as a "flattened, oval, elongate sole." The sole extends forwards below the head. It is covered in large thin scales that increase in pigmentation in the distal parts. The back and sides of this fish are dark and the snout translucent, and there are several large melanophores behind and below the head. ''Opisthoprocus soleautus'' has a specialized modifica ...

Dolichopteryx Longipes
The brownsnout spookfish or brown-snout spookfish (''Dolichopteryx longipes'') is a species of barreleye in the family Opisthoproctidae. It and the glasshead barreleye fish are the only vertebrates known to employ a mirror, in addition to a lens, to focus an image in its eyes. This species probably has a worldwide tropical and temperate distribution; in the Atlantic Ocean it is known from Bermuda, the Bahamas, the Greater Antilles, and the Gulf of Mexico, and in the Pacific Ocean it is known from the California Current region and the South China Sea. It is found in the mesopelagic and bathypelagic zones at a depth of , but usually occurs below . In the Gulf of Mexico it is found shallower, at . Description The body of ''D. longipes'' is slender, the depth 12.6–14.3% of the standard length. The head comprises 29-32.4% of the standard length, with a long, pointed snout. The eyes are cylindrical and face upward, with an accessory outgrowth to the side, and are covered with a silve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argentiniformes
The Argentiniformes are an order of ray-finned fish whose distinctness was recognized only fairly recently. In former times, they were included in the Osmeriformes (typical smelt and allies) as suborder Argentinoidei. That term refers only to the suborder of marine smelts and barreleyes in the classification used here, with the slickheads and allies being the Alepocephaloidei. These suborders were treated as superfamilies Argentinoidea and Alepocephaloidea, respectively, when the present group was still included in the Osmeriformes. They contain six or seven families with almost 60 genera and at least 228 species. A common name for the group is marine smelts and allies, but this is rather misleading since the "freshwater" smelts of the Osmeridae also live predominantly in the ocean.FishBase (2006)Order Osmeriformes Version of 2006-OCT-09.

Monacoa
''Monacoa'' is a genus of fish in the family Opisthoproctidae found in Atlantic and Pacific Oceans. They are also known as long-nosed mirrorbellies or simply mirrorbellies, in reference to the bioluminescent organ in their intestines. The largest species, '' Monacoa grimaldii'', can grow to standard length. Species There are currently 3 recognized species in this genus: * '' Monacoa grimaldii'' ( Zugmayer, 1911) (mirrorbelly) * '' Monacoa griseus'' J. Y. Poulsen, Sado, C. Hahn, Byrkjedal, Moku & Miya, 2016 (grey mirrorbelly) * '' Monacoa niger'' J. Y. Poulsen, Sado, C. Hahn, Byrkjedal, Moku & Miya, 2016 (black mirrorbelly) Until 2016, it was believed there was a single species of ''Monacoa'', but in 2016 it was determined that there are actually 3 distinct species. The ''M. griseus'' and ''M. niger'' are distinct from the ''M. grimaldii'' because of their differences in pigmentation.

Macropinna
Pacific Barreleye Fish (''Macropinna'') is a genus of ray-finned fish belonging to Opisthoproctidae, the barreleye family. It contains one species, ''M. microstoma''. It is recognized for a highly unusual transparent, fluid-filled shield on its head, through which the lenses of its eyes can be seen. It was originally believed that the tubular eyes of this fish were fixed in place and, therefore, only provided a tunnel vision view of what was seen above its head. However, in 2008, scientists discovered that its eyes were able to rotate both up and forward in its transparent shield. ''M. microstoma'' has a tiny mouth and most of its body is covered with large scales. The fish normally hangs nearly motionless in the water, at a depth of about to , using its large fins for stability and with its eyes directed upward. In the low light conditions it is assumed the fish detects prey by its silhouette. MBARI researchers Bruce Robison and Kim Reisenbichler observed that when prey such as ...
