Aetobatus
''Aetobatus'' is a genus of eagle rays native to the Atlantic, Pacific and Indian Oceans. It was formerly placed in Myliobatidae, but is now placed in its own family Aetobatidae based on salient differences from myliobatids, especially the pectoral fins joining the head at the level of the eyes.White, W.

Aetobatus Narinari
The spotted eagle ray (''Aetobatus narinari'') is a cartilaginous fish of the eagle ray family, Aetobatidae. As traditionally recognized, it is found globally in tropical regions, including the Atlantic, Pacific and Indian Oceans. Recent authorities have restricted it to the Atlantic (including the Caribbean Sea, Caribbean and Gulf of Mexico) with other populations recognized as the ocellated eagle ray (''A. ocellatus'') and Pacific white-spotted eagle ray (''A. laticeps''). Spotted eagle rays are most commonly seen alone, but occasionally swim in groups. They are ovoviviparous, the female retaining the eggs then releasing the young as miniature versions of the parent. This ray can be identified by its dark Dorsum (anatomy), dorsal surface covered in white spots or rings. Near the base of the ray's relatively long tail, just behind the pelvic fins, are several venomous, barbed stingers. Spotted eagle rays commonly feed on small fish and crustaceans, and will sometimes dig with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aetobatus Flagellum
The longheaded eagle ray (''Aetobatus flagellum'') is a species of eagle ray in the family Myliobatidae. The longheaded eagle ray, like other members of the genus Aetobatus, is characteristically different from other genera of eagle rays, distinguished by their notched nasal curtain; complete, singular set of upper and lower teeth; and v-shaped teeth in the lower jaw. It is found in the tropical and warm temperate Indo-West Pacific. It formerly included populations in the northwest Pacific, but these were recognized as a separate species, ''Aetobatus narutobiei'', in 2013. Longheaded eagle rays are benthopelagic fishes that feed on crustaceans, cephalopods, echinoderms, and small bony fishes. It is a poorly known species, but generally uncommon and considered Endangered species, endangered by the IUCN. Description Longheaded eagle rays have a prominent cephalic fin attached to the snout, projecting up and away from the head. Eyes are located laterally on the dorsal side of the hea ...

Aetobatus Ocellatus
The ocellated eagle ray or the whitespotted eagle ray, ''Aetobatus ocellatus'', is a species of cartilaginous fish in the eagle ray family Myliobatidae. It is found in the tropical Indo-West Pacific region. In the past it was included in the spotted eagle ray (''A. narinari''), a species restricted to the Atlantic after the split.White, W.T., P.R. Last, G.J.P. Naylor, K. Jensen & J.N. Caira (2010).

Aetobatus Laticeps
''Aetobatus laticeps'', the Pacific white-spotted eagle ray, is a species of cartilaginous fish in the eagle ray family Myliobatidae. It is found in the tropical East Pacific Ocean, ranging from Baja California to northern Peru, including the Galápagos. There has been recent evidence to suggest ''A.laticeps'' is in the Mexican tropical Pacific, more specifically in Chacahua Lagoon. However this evidence is insufficient and so the research being done on the spotted eagle rays in Chacahua Lagoon is working under the name ''A. narinari.'' Until 2014, it was included in the similar spotted eagle ray (''A. narinari''), but the two differ in genetics. Studies have been conducted to attempt to identify spot patterns at the individual level. ''A. laticeps'' and ''A. narinari'' both have white spots on the dorsal side of their dark body, making them difficult to differentiate. Following the split, ''A. narinari'' is restricted to the Atlantic, while the Indo-Pacific The Indo-Paci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aetobatus Narutobiei
''Aetobatus narutobiei'', the Naru eagle ray, is a species of cartilaginous fish of the eagle ray family, Myliobatidae. It is found in the northwest Pacific off south Japan, South Korea, China, Hong Kong and Vietnam. It occurs from shallow, coastal flats to a depth of , but always in water warmer than . Until 2013, this species was included in the longheaded eagle ray (''Aetobatus flagellum''), but the two differ in genetics, morphology, size and range (the smaller longhead eagle ray is from the Indian Ocean). The Naru eagle ray is up to in width and its upperparts are uniformly greenish grey to brownish. Although little information exists for this species throughout most of its range, the life history and ecology has been reasonably well studied in Japanese waters. In the Ariake Bay region of Kyushu Island where it is numerous, it is considered a pest that preys on commercially valuable farmed bivalve Bivalvia () or bivalves, in previous centuries referred to as the ...

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 ...
