batoidea

Recent molecular studies suggest the Batoidea are not derived selachians as previously thought.

A variety of sharks used to feed on Batoidea, which are a main predator of bay scallops.

Rajiformes is one of the four orders in the superorder Batoidea, flattened cartilaginous fishes related to sharks.

Superorder Batoidea (rays and skates), containing the orders:

Skates are cartilaginous fish belonging to the family Rajidae in the superorder Batoidea of rays.

Subdivision Batoidea (rays)

It includes the Squatiniformes, and the Pristorajea, which may also be invalid, but includes the Pristiophoriformes and the Batoidea.

Extant species are classified under Selachii (Selachimorpha), the modern sharks, and Batoidea, the rays, skates and sawfish.

Ischyrhiza is an extinct genus of cartilaginous fish from the Cretaceous and Paleogene belonging to the primitive Batoidea family Sclerorhynchidae.

The flaps along its body could probably be moved in a wave-like formation, allowing it to swim quickly or to 'hover', as in Batoidea (rays) or cuttlefish.

The radiation of elasmobranches in the chart on the right is divided into the taxa: Cladoselache, Eugeneodontiformes, Symmoriida, Xenacanthiformes, Ctenacanthiformes, Hybodontiformes, Galeomorphi, Squaliformes and Batoidea.

Those spotted on the 'house reef' include: parrot fish, marine angelfish, butterflyfish, tuna, ray or batoidea, smaller shark, cuttlefish, porcupinefish, wrasse, clownfish, damselfish, octopus, surgeonfish, unicornfish, crab, moray eel and many more.

The knifetooth sawfish (Anoxypristis cuspidata), also known as the pointed sawfish or narrow sawfish, is a species of sawfish in the family Pristidae, part of the Batoidea, a superorder of cartilaginous fish that includes the rays and skates.
