Shorthorn Devil Ray
Also known as the lesser devilray, the shortfin devil ray is an uncommon, inshore species found in areas of the Indian Ocean and the western central Pacific Ocean. In South Africa, it occurs only in KwaZulu-Natal, where it is believed to be on the very edge of its
range. This species lives in schools, and often breaches clear of the water. It feeds on planktonic crustaceans, and grows up to a maximum disc width of 119 centimetres. The shortfin devil ray is ovoviviparous, meaning that it creates one egg that hatches within the mother to produce a single live pup. At birth, the pup already has a disc width of 30 centimetres. This species is dark brown above and white below, with a white-tipped dorsal fin, slightly curved pectoral fins and a short head with short cephalic fins.
Pygmy Devil Ray
Sometimes referred to as the longhorned pygmy devil ray, this is a relatively little-known species believed to be locally common in areas of the Indo-West Pacific and the northern Indian Ocean. However, it is a likely victim of commercial by-catch, and
is therefore listed on the IUCN Red List as Near Threatened. The pygmy devil ray favours coastal continental waters, and has a maximum disc width of around 100 centimetres. Brownish-grey on top and whitish underneath, it can be identified by the semicircular black blotch on the anterior edge of its pectoral fins. This species is ovoviviparous, which means that it produces an egg that hatches inside the female so that she gives birth to a single live offspring. These rays feed near the surface on plankton and small fish.
