The IUCN also lists 12 fish subspecies as data deficient. Of the subpopulations of fishes evaluated by the IUCN, 34 species subpopulations have been assessed as data deficient. This is a complete list of data deficient fish species and subspecies evaluated by the IUCN. Species and subspecies which have data deficient subpopulations (or stocks) are indicated. Cartilaginous fishes Chondrichthyes includes sharks, rays, skates, and sawfish. There are 475 species and three subpopulations of cartilaginous fish evaluated as data deficient.

Narke Dipterygia
The numbray or spottail sleeper ray (''Narke dipterygia'') is a species of electric ray in the family Family (from la, familia) is a Social group, group of people related either by consanguinity (by recognized birth) or Affinity (law), affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its ... Narkidae. It may be found in shallow muddy estuaries or offshore depths. It is a weak swimmer that lies on the bottom, commonly buried. It eats small marine invertebrates and fish. It pounces on its prey and wraps its body around its prey, killing or stunning it with electrical shocks. It has been observed that Numbrays are not as common as other types of rays in the area around the Indian Ocean. This can be attributed to the relatively large doubling time for a population, reaching up to 18 years. References Momeninejad, Ali & Keivany, Yazdan & Sultan-Mohammadi, Vahid. (2014).

Glaucostegus Halavi
The halavi guitarfish (''Glaucostegus halavi'') is a species of ray found in the Indo-West Pacific (Red Sea to Gulf of Oman, with unconfirmed records in the area east of Oman). Recorded twice, in 1997 and 2004, in the levantine waters, the question of its permanent settlement in the Mediterranean Sea remains open. Its name is derived from the Arabic word (''halawi'').an Arabic zoological dictionary by Maj. - General Amin Malouf, M.

Pteromylaeus Bovinus
''Aetomylaeus bovinus'', also known as the bull ray, is a species of large stingray of the family Myliobatidae found around the coasts of Europe and Africa. Biology and ecology The species is ovoviviparous and reach sexual maturity at 4 to 6 years old. With a low fecundity of three to four pups per litter and a long gestation of 6 to 12 months (depending on the geographical zone), this species have a very sensitive life history. Very little is known concerning the ecology and behavior of ''A. bovinus'', however it is part of the coastal marine megafauna, with a maximum length of 222 cm (87.4 in) and 116 kg (225.7 lbs), bull rays can be considered as giants of the shallow waters. Their maximum length and very narrow depth range of 0 to 30 m exposes them to various threats. Indeed, large-body, shallow-water species are at greatest risk of threats. Bull ray appears to be extremely rare throughout the Mediterranean region and its current population trend is highly sus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Myliobatis Tobijei
The Japanese eagle ray (''Myliobatis tobijei''), also known as the cowhead eagle ray or kite ray is a ray species in the family Myliobatidae. Description The Japanese eagle ray grows to be up to 150 centimeters long, and has a disc at least 114 centimeters wide. It is yellow-brown in color, and usually contains darker spots. It has rather long stinging spines, and its claspers are less than one-tenth the width of its disc. Each jaw of the species contains 7 rows of teeth. Behavior The Japanese eagle ray is demersal, usually inhabiting sea floors and feeding on benthic animals. In particular, it is known to eat crustaceans, fish, and sometimes benthic plants. Like all mylobatids, the species is ovoviviparous. Embryos initially feed on yolk. They later receive nourishment by indirectly absorbing uterine fluid from their mother. Little else is known about the biology of this species. Distribution, threats, and conservation The Japanese eagle ray lives in the waters of ...

It can be differentiated from the similar Chilean eagle ray (''M. chilensis'') by color and rostral fin form. The ray has not been extensively studied, and is ranked as Data Deficient by the IUCN. It has been recorded only in the open ocean, but is considered likely to be a benthic feeder. It is thought by scientists to be similar to other myliobatids in terms of biology, habits, and threats.

Southern Eagle Ray
The Southern eagle ray (''Myliobatis goodei''), sometimes known as the Southern eagle fish or the rockfish, is a ray species in the family Myliobatidae. It lives in waters just off of the Atlantic coast, from the tip of Florida down to Argentina, inhabiting estuaries or bays to give birth during spring and summer and migrating to the open sea in autumn and winter. It has an average width of 99 centimeters, and a length of 60 centimeters. It is often confused with the bullnose ray, a related species in the genus ''Myliobatis'', due to the two species' similarities in appearance. Taxonomy Samuel Garman described the southern eagle ray in 1885. Distribution and habitat The Southern eagle ray lives on various parts of the Atlanta coast. Sightings have been reported from the coast of Southern Mexico all the way down to Argentina, as well as on the coast of Florida. The specific countries that the Southern eagle ray is native to are Argentina, Belize, Brazil, Colombia, Costa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
