Life of Blue Spotted Stingray

Life of Sea | Blue Spotted Stingray (Taeniura lymma) | Blue spotted stingray is also known as Blue-spotted fantail ray, Blue spotted stingray, Blue spotted ray, and Ribbontail stingray. Blue spotted stingrays are bottom-dwelling species. They are comonnly found in coral reefs and adjacent sandy flats. They are only rarely found buried under the sand. In the Indo-West Pacific they are found in the Red Sea and East Africa to the Solomon Islands, north to southern Japan, and southern to northern Australia.

Blue spotted stingrays are colorful stingray with large bright blue spots on an oval, elongated disc and blue side-stripes along the tail. The snout is rounded and angular and the disc has broadly rounded outer corners. They have a short tapering tail that is less than twice the body length when intact, with a broad lower caudal finfold that extends to the tail tip. The disc has no large thorns but does have small, flat denticles along the midback in adults. There is usually 1 medium-sized stinging spine on the tail found further from the base than most stingrays. They are gray-brown to yellow, or olive-green to reddish brown in color on the dorsal side, white on the ventral side. They reach a maximum length about 70 cm.

Blue spotted stingray migrates in groups into shallow sandy areas during the rising tide to feed on mollusks, worms, shrimps, and crabs. They disperse at low tide to seek shelter in caves and under ledges. Its predators include Hammerhead sharks and Bottlenose dolphins. It is also potentially preyed upon by other large fishes and marine mammals. At night, small groups assemble and swim onto shallow sandy flats with the rising tide to feed. Unlike many other stingrays, this species seldom buries itself in sand.

Blue spotted stingray is capable of inflicting an excruciating wound with its venomous tail spines. Its attractive appearance and relatively small size has resulted in its being the most common stingray found in the home aquarium trade. Blue spotted stingray is fairly easy to keep once it is feeding on it's own. You can feed them all kinds of large meaty foods like small pieces of fish, squid, shrimp, crabs, prawns, molluscs, and live goldfish. It is best to feed small amounts several times a day. Water in the aquarium should not be from the tap due to trace amounts of copper and other contaminants. It is best to use reverse osmosis or deionized. Blue spotted stingray is utilized as food in East Africa, Southeast Asia, and Australia. It is captured intentionally or incidentally using gillnets, longlines, spears, and fence traps
