Batoids are flat-bodied, and, like sharks, are cartilaginous fish, meaning they have a boneless skeleton made of a tough, elastic cartilage. Most batoids have five ventral slot-like body openings called gill slits that lead from the gills , but the Hexatrygonidae have six. [ 3 ]
Batoids are a superorder of cartilaginous fish consisting of skates, rays and other fish all characterized by dorsoventrally flattened bodies and large pectoral fins fused to the head. This distinctive morphology has resulted in several unique forms of locomotion. Most Batoids exhibit median paired fin swimming, utilizing their enlarged ...
Rajiformes / ˈ r æ dʒ ɪ f ɔːr m iː z / is one of the four orders in the clade Batomorphi, often referred to as the superorder Batoidea, flattened cartilaginous fishes related to sharks. [2] Rajiforms are distinguished by the presence of greatly enlarged pectoral fins , which reach as far forward as the sides of the head, with a generally ...

79 living species of sharks have been featured in Shark Week, along with several species of batoids (rays and kin), chimaeras, and extinct forms. The most common species to be featured are great white sharks ( Carcharodon carcharias , 18.4% of episodes), tiger sharks ( Galeocerdo cuvier , 12.2%), bull sharks ( Carcharhinus leucas , 9.6%), and ...

Among the marine fishes, sharks and batoids (rays and skates) form a considerable diversity. [2] A preliminary checklist of sharks around Sri Lanka was compiled by marine biologist, ornithologist, astronomer and well known diver Rex I. De Silva in 1985. It is cited as the first most comprehensive catalogue to Sri Lankan cartilage fishes.
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 ...
