: ''Not to be confused with the bluespotted stingray, ''Neotrygon kuhlii. The bluespotted ribbontail ray (''Taeniura lymma'') is a species of stingray in the family Dasyatidae. Found from the intertidal zone to a depth of , this species is common throughout the tropical Indian and western Pacific Oceans in nearshore, coral reef-associated habitats. It is a fairly small ray, not exceeding in width, with a mostly smooth, oval pectoral fin disc, large protruding eyes, and a relatively short and thick tail with a deep fin fold underneath. It can be easily identified by its striking color pattern of many electric blue spots on a yellowish background, with a pair of blue stripes on the tail. 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. When the tide recedes, the rays separate and withdraw to shelters on the reef. Reproduction is aplacental viviparous, with females giving birth to litters of up to seven young. This ray is capable of injuring humans with its venomous tail spines, though it prefers to flee if threatened. Because of its beauty and size, the bluespotted ribbontail ray is popular with private aquarists despite being poorly suited to captivity. The International Union for Conservation of Nature (IUCN) has listed this species as Near Threatened, as it faces widespread habitat degradation and intensive fishing pressure throughout its range. == Taxonomy and phylogeny == The bluespotted ribbontail ray was originally described as ''Raja lymma'' by Swedish naturalist Peter Forsskål, in his 1775 ''Descriptiones Animalium quae in itinere ad maris australis terras per annos 1772, 1773, et 1774 suscepto collegit, observavit, et delineavit Joannes Reinlioldus Forster, etc., curante Henrico Lichtenstein''.〔Eschmeyer, W.N. and R. Fricke, eds. (''lymma, Raja'' ). Catalog of Fishes electronic version (January 15, 2010). Retrieved on February 17, 2010.〕 The specific epithet ''lymma'' means "dirt". Forsskål did not designate a type specimen.〔 In 1837, German biologists Johannes Peter Müller and Friedrich Gustav Jakob Henle created the genus ''Taeniura'' for ''Trygon ornatus'', now known to be a junior synonym of this species.〔Eschmeyer, W.N. and R.

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''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「: ''Not to be confused with the bluespotted stingray, ''Neotrygon kuhlii.The bluespotted ribbontail ray (''Taeniura lymma'') is a species of stingray in the family Dasyatidae.
