1. They use electroreception to help locate prey, picking up on subtle temperature differences and electrical fields generated by other animals in the sand. Reproduction is aplacental viviparous, with females giving birth to litters of up to seven young. We have already protected nearly 4 millionsquare miles of ocean and innumerable sea life - but there is still more to be done. Bluespotted Ribbontail Ray Posted on January 15, 2019 January 16, 2019 by Asrar Makrani Bluespotted ribbontail ray (Taeniura lymma), mostly found in the waters of South East Asia, is not exactly endangered but due to overfishing and habitat loss, it is at the threat of extinction. The lower jaw dips at the middle and deep furrows are present at the mouth corners. Females bear litters of up to seven young, each a miniature version of the adult measuring around 1314cm (5.15.5in) across. These rays have an electroreceptor system, which they use to find prey and communicate with other members of their species. [8] Numerous parasites have been identified from this species: the tapeworms Aberrapex manjajiae,[17] Anthobothrium taeniuri,[18] Cephalobothrium taeniurai,[19] Echinobothrium elegans and E. helmymohamedi,[20][21] Kotorelliella jonesi,[22] Polypocephalus saoudi,[23] and Rhinebothrium ghardaguensis and R. taeniuri,[24] the monogeneans Decacotyle lymmae,[25] Empruthotrema quindecima,[26] Entobdella australis,[27] and Pseudohexabothrium taeniurae,[28] the flatworms Pedunculacetabulum ghardaguensis and Anaporrhutum albidum,[29][30] the nematode Mawsonascaris australis,[31] the copepod Sheina orri,[32] and the protozoan Trypanosoma taeniurae. It is rare in the Persian Gulf and Gulf of Oman. Known scientifically as the Taeniura lymma, the bluespotted ribbontail ray is a small species of stingray that can be found throughout most shallow waters found within the tropical Indo-Pacific region.It can be found as shallow as the intertidal zone, to a maximum depth of around 30 metres. Habitat. It is a bottom-dwelling inhabitant of lagoons, estuaries, and reefs, generally at a depth of 2060 m (66197 ft). It is also commonly encountered in the intertidal zone and tidal pools, and has been sighted near seagrass beds. Although relatively common and widely distributed, this species faces continuing degradation of its coral reef habitat throughout its range, from development and destructive fishing practices using cyanide or dynamite. [12], While timid and innocuous towards humans, the bluespotted ribbontail ray is capable of inflicting an excruciating wound with its venomous tail spines. 2. Because of its beauty and size, the bluespotted ribbontail ray is popular with private aquarists despite being poorly suited to captivity. If cornered they can lash out with the poisoned barb on the end of their tails, and that venom can prove fatal to many species, including humans.3, Blue spotted ribbontail rays reproduce via eggs that grow inside the mothers body for a period of four months to a year, and live rays are born shortly after hatching inside the mother.4. [5] Morphological examination has suggested that the bluespotted ribbontail ray is more closely related to the amphi-American Himantura (H. pacifica and H. schmardae) and the river stingrays (Potamotrygonidae) than to the congeneric blotched fantail ray (T. meyeni), which is closer to Dasyatis and Indo-Pacific Himantura. These rays are threatened around the world due to destructive fishing practices and habitat loss.1 They are also sometimes traded in the private aquarium trade, though these rays rarely thrive in captivity. Other common names include bluespotted stingray and blue-spotted maskray. May be confused with the bluespotted ribbontail ray, Taeniura lymma, although blue-spotted stingray has a more angular disc and narrower tail with conspicuous black and white rings. (2009). [13][16] When threatened, this ray tends to flee at high speed in a zigzag pattern, to throw off pursuers. At night, small groups of bluespotted ribbontail rays follow the rising tide onto sandy flats to root for small benthic invertebrates and bony fishes in the sediment. 1 They are also sometimes traded in the private aquarium trade, though these rays rarely thrive in captivity. The tail has two stripes of the same blue running along each side as far as the spines. There is a narrow flap of skin between the nares with a fringed posterior margin, reaching past the mouth.
