Blue Stingrays (Dasyatis chrysonota) are coming every spring in October into the Knysna Lagoon. They can be best viewed at the Knysna Waterfront when the tide is coming in. Then they usually gather under the little jetty close to the Knysna harbour. Sometimes there are groups of up to 50 stingrays.
Previously this species was confused with Dasyatis pastinaca and Dasyatis marmorata, which do not occur in the area. Dasyatis chrysonata occur from Angola to at least St. Lucia, Natal, South Africa, possibly extending to Mozambique and beyond up to about 100 m depth.
Feeding at surface in 10-15 meters of sandy bottom, off Mogote Peninsula near La Paz, Baja California Sur. Area rich in plankton where juvenile whale sharks come to feed every year.

The cowtail stingray, Pastinachus sephen, is a species of stingray in the family Dasyatidae, widespread in the Indo-Pacific region and occasionally entering freshwater habitats. Other common names include banana-tail ray, drab stingray, fantail ray, feathertail stingray, and frill tailed sting ray. This species is sometimes placed in the genus Dasyatis or Hypolophus (an obsolete synonym of Pastinachus). The most distinctive characteristic of the cowtail stingray is the large, flag-like ventral fold on its tail, which is especially prominent when the ray is swimming. This species is targeted by commercial fisheries as a source of high-quality shagreen, a type of leather, and its populations are now under threat from heavy exploitation.

Rajiformes is one of the four orders in the superorder Batoidea, 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 head and the gill slits are...
