Myliobatis Goodei
The Southern eagle ray (''Myliobatis goodei''), sometimes known as the Southern eagle fish or the rockfish, is a Batoidea, 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, C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myliobatis Aquila
The common eagle ray or bullray (''Myliobatis aquila'') is a species of fish in the family Myliobatidae. It inhabits the eastern Atlantic Ocean (North Sea to South Africa), the Mediterranean Sea and the south-western Indian Ocean. Description The common eagle ray reaches up to in total length and has a disc width up to .Muus, B., J. G. Nielsen, P. Dahlstrom and B. Nystrom (1999). ''Sea Fish.'' p. 76. Most specimens are, however, smaller. Females grow to be larger than males. The dorsal surface is brown or black while the ventral surface is white. It has a rhomboidal disc with a pair of large, triangular pectoral fins projecting on either side, and a single dorsal fin. The blunt snout is rounded and the tail is long and slender, with a large spine at its base but no tail fin. On average, males have 72 spine serrations and females have 66 spine serrations. The spine makes about 70% of the male's length and 65% of the female's length. The mid dorsal groove, which contains the glan ...

Eagle Ray
The eagle rays are a group of cartilaginous fishes in the family Myliobatidae, consisting mostly of large species living in the open ocean rather than on the sea bottom. Eagle rays feed on mollusks, and crustaceans, crushing their shells with their flattened teeth. They are excellent swimmers and are able to breach the water up to several meters above the surface. Compared with other rays, they have long tails, and well-defined, rhomboidal bodies. They are ovoviviparous, giving birth to up to six young at a time. They range from in length and 7 m (23 ft) in wingspan. Classification Nelson's book ''Fishes of the World'' treats cownose rays, mantas, and devil rays as subfamilies in the Myliobatidae. However, most authors (including William Toby White) have preferred to leave the Rhinopteridae and Mobulidae outside of the Myliobatidae. White (2014) retained three genera (''Aetobatus'', ''Aetomylaeus'', and ''Myliobatis'') in the Myliobatidae, while a fourth (''Pteromylaeu ...

Myliobatis Hamlyni
The purple eagle ray (''Myliobatis hamlyni'') is a species of fish in the family Myliobatidae. It was formerly considered endemic to Australia but is now known to be more widespread. Its natural habitat is the open seas where it has a patchy distribution, and the International Union for Conservation of Nature has assessed its conservation status as being "near-threatened". Taxonomy The purple eagle ray was first described in 1911 by the Australian ichthyologist James Douglas Ogilby as ''Myliobatis hamlyni'', being named in honour of his friend, the entomologist Ronald Hamlyn-Harris, who was director of the Queensland Museum from 1910 to 1917. This eagle ray was originally thought to be endemic to eastern Australia, with other records from the region being ascribed to the closely related Japanese eagle ray (''Myliobatis tobijei''). However a redescription of both species in 2016, including a molecular analysis, indicated that previous records from Western Australia, Indonesia, ...

Myliobatis Australis
The New Zealand eagle ray or Australian eagle ray (''Myliobatis tenuicaudatus'') is an eagle ray of the family Myliobatidae, found in bays, estuaries, and near rocky reefs around New Zealand and southern Australia on the inner continental shelf. It is a common species and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern". Taxonomy ''Myliobatis tenuicaudatus'' was first described in 1877 by the Scottish naturalist James Hector, who was director of the geological survey of New Zealand; the fish was thought to be endemic to New Zealand. Subsequently, in 1881, the Australian zoologist William John Macleay described ''Myliobatis australis'' from the waters of Southern Australia as a new species. In a generic revision in 2014, W.T. White determined that the two are synonymous, and that ''M. australis'' is a junior synonym of ''M. tenuicaudatus''. Description The New Zealand eagle ray is a cartilaginous fish with a ro ...

Founded in 1948, IUCN has become the global authority on the status .... 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.
