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 (sixgill stingray), Plesiobatidae (deepwater stingray), Urolophidae (stingarees), Urotrygonidae (round rays), Dasyatidae (whiptail stingrays), Potamotrygonidae (river stingrays), Gymnuridae (butterfly rays ...
Batomorphi is a division [2] 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. [3]
This species is a solid gray, brown, reddish, or olive-green above, and whitish below with dark fin margins. Young rays may have white spots. [13] [15] The largest recorded common stingray specimen was found in 2016 in the İzmir Province of Turkey in the course of a study on trolling. Its fins had a width of 2.21 metres (7.3 ft), although its ...
Potamotrygon leopoldi is part of a species complex of blackish river rays with contrasting pale spots found in the Tapajós, Xingu and Tocantins basins [3]. River stingrays are almost circular in shape, and range in size from Potamotrygon wallacei, which reaches 31 cm (1.0 ft) in disc width, [9] to the chupare stingray (S. schmardae), which grows up to 2 m (6.6 ft) in disc width.

Camouflaged porcupine ray. Myliobatiformes (/ m ɪ l i ˈ ɒ b ə t ɪ f ɔːr m iː z /) 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 ...
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 (0.59 to 6.56 ft) or more across in the case of the smalleye stingray and giant freshwater stingray.
