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. [2] They and their close relatives, the sharks, compose the subclass Elasmobranchii. Rays are the largest group of cartilaginous fishes ...
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 ...
It is fairly large for a ray, at 170 centimetres (67 in) in length. Aellopobatis is characterized by an extremely elongated rostrum. It also has a large, heart-shaped disc and a long, narrow tail. It has two similarly-sized dorsal fins located posterior to the pelvic fin radials. In male specimens, the claspers are long and slender. [1]
Measuring between 15 and 80 cm (5.9 and 31.5 in) long, these rays have oval to diamond-shaped pectoral fin discs and relatively short tails that terminate in leaf-shaped caudal fins, and may also have small dorsal fins and lateral skin folds. Most are smooth-skinned, and some have ornate dorsal color patterns.
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 their 2025 description of Apolithabatis, Türtscher et al. analyzed most of the Jurassic European holomorphic ray fossils. Their phylogenetic analysis placed all of these taxa in a monophyletic clade at the base of Batomorphi, outside of the crown group (all of the extant rays and their closest relatives). As such, they established the new ...
The butterfly rays are the rays forming the genus Gymnura and the family Gymnuridae. They are found in warm oceans worldwide, and occasionally in estuaries . The body of butterfly rays is flattened and surrounded by an extremely broad disc formed by the pectoral fins , which merge in front of the head.
