Descrizione Rajiformes
High Quality Content by WIKIPEDIA articles! Rajiformes is one of the four orders of batoids, flattened cartilaginous fishes related to sharks. 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 flattened body. The undulatory pectoral fin motion diagnostic to this taxon is known as rajiform locomotion. The eyes and spiracles are located on the upper surface of the body, and the gill slits on the underside. They have flattened, crushing teeth, and are generally carnivorous, although manta rays are filter feeders. Most species give birth to live young, although some lay eggs with a horny capsule ("mermaid's purse").
