Myliobatiformes ( /mɪliˈɒbətɪfɔːrmz/ ) is one of the four orders of batoids, cartilaginous fishes related to sharks. [2] [3] They were formerly included in the order Rajiformes, but more recent phylogenetic studies have shown the myliobatiforms to be a monophyletic group, and its more derived members evolved their highly flattened shapes independently of the skates. [4] [5]

Classification

Myliobatiformes is classified as follows in Eschmeyer's Catalog of Fishes: [6]

    The family Aetobatidae is recognised by some authorities. It contains the genus Aetobatus, which is otherwise part of Myliobatinae. [7]

    The families Myliobatidae and Rhombodontidae are sometimes grouped in their own superfamily, Myliobatoidea. [8]

    Stingrays are a group of sea rays, a type of cartilaginous fish. They are classified in the suborder Myliobatoidei of the order Myliobatiformes and consist of eight families: Hexatrygonidae, Plesiobatidae, Urolophidae (stingarees), Urotrygonidae, Dasyatidae, Potamotrygonidae, Gymnuridae and Myliobatidae .

    <span class="mw-page-title-main">Spotted eagle ray</span> Species of fish

    The spotted eagle ray 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 with other populations recognized as the ocellated eagle ray and Pacific white-spotted eagle ray. 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.

    <span class="mw-page-title-main">Longheaded eagle ray</span> Species of cartilaginous fish

    The longheaded eagle ray 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 by the IUCN.

    <i>Aetobatus</i> Genus of cartilaginous fishes

    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.

    The chupare stingray or Caribbean whiptail stingray is a species of stingray in the family Potamotrygonidae, found in the western Atlantic Ocean from the Gulf of Campeche to Brazil, including the Antilles. The presence of this species in the Gulf of Mexico has not been confirmed. It also occurs in the Bahamas. It usually inhabits sandy substrates, sometimes near coral reefs, and is an infrequent visitor to the Amazon River estuary. Leonard Compagno doubted the taxonomic validity of this species in his 1999 Checklist of Living Elasmobranchs.

    <span class="mw-page-title-main">Porcupine ray</span> Species of cartilaginous fish

    The porcupine ray is a rare species of stingray in the family Dasyatidae. This bottom-dweller is found throughout the tropical Indo-Pacific, as well as off West Africa. It favors sand, coral rubble, and seagrass habitats in inshore waters to a depth of 30 m (100 ft). A large and heavy-bodied species reaching 1.2–1.5 m (3.9–4.9 ft) in width, the porcupine ray has a nearly circular, plain-colored pectoral fin disc and a thin tail without any fin folds. Uniquely within its family, it lacks a venomous stinging spine. However, an adult ray can still defend itself ably with the many large, sharp thorns found over its disc and tail.

    <span class="mw-page-title-main">Whiptail stingray</span> Family of fishes

    The whiptail stingrays are a family, the Dasyatidae, of rays in the order Myliobatiformes. They are found worldwide in tropical to temperate marine waters, and a number of species have also penetrated into fresh water in Africa, Asia, and Australia. Members of this family have flattened pectoral fin discs that range from oval to diamond-like in shape. Their common name comes from their whip-like tails, which are much longer than the disc and lack dorsal and caudal fins. All whiptail stingrays, except the porcupine ray, have one or more venomous stings near the base of the tail, which is used in defense. In order to sting their victims, they jerk their tails as the stinger falls off and stays in the wound that they have created. The stinger of a whiptail stingray is pointy, sharp with jagged edges. They range in size from 0.18 to 2.0 m or more across in the case of the smalleye stingray and giant freshwater stingray.

    The Pacific chupare or Pacific whiptail stingray is a species of stingray in the family Potamotrygonidae. It has been reported off the Pacific coast of Central America from Oaxaca, Mexico to Costa Rica, and also around the Galapagos Islands. It is usually found in shallow water on soft silty or muddy flats; it is unknown whether this species is tolerant of low salinity like the related chupare stingray. Leonard Compagno doubted the taxonomic validity of this species in his 1999 Checklist of Living Elasmobranchs.

    Batomorphi is a clade of cartilaginous fishes, commonly known as rays, this taxon is also known as the superorder Batoidea, but the 5th edition of Fishes of the World classifies it as the division Batomorphi. They and their close relatives, the sharks, compose the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes, with well over 600 species in 26 families. Rays are distinguished by their flattened bodies, enlarged pectoral fins that are fused to the head, and gill slits that are placed on their ventral surfaces.

    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 species restricted to the Atlantic after the split.

    <i>Hypanus</i> Genus of cartilaginous fishes

    <i>Aetobatus laticeps</i> Species of cartilaginous fish

    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, 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 is inhabited by the closely related A. ocellatus.

    <i>Dasyomyliobatis</i> Extinct genus of cartilaginous fishes

    Dasyomyliobatis is an extinct stingray genus in the monotypic family Dasyomyliobatidae, of the order Myliobatiformes. It contains a single species, D. thomyorkei, known from the Eocene Monte Bolca Lagerstätte of Italy. The specific epithet references the English musician and Radiohead vocalist Thom Yorke.
