Bluespotted stingray
The bluespotted stingray (''Neotrygon kuhlii'') or Kuhl's stingray, is a species of stingray of the Dasyatidae family. It was recently changed from ''Dasyatis kuhlii'' in 2008 after morphological and molecular analyses show that it is part of a distinct genus, Neotrygon. The body is rhomboidal and colored green with blue spots. Maximum disk width is estimated . It is popular in aquaria but usually not distinguished from the bluespotted ribbontail ray. The ribbontail has a rounded body, is a brighter green with brighter blue and more vivid spots, but the bluespotted stingray is larger. The stingray's lifespan is estimated thirteen years of age for females and ten years for males. The bluespotted stingray preys on many fish and small mollusks. The bluespotted stingray is also generally found from Indonesia to Japan, and most of Australia. The bluespotted stingray is also targeted by many parasites such as tapeworms, flatworms, and flukes.
==Taxonomy==
The bluespotted stingray was discovered by Heinrich Kuhl in Java, Indonesia. The population of this species is greatly debatable due to the five different species of rays in Indonesia. Also, there are two different subgroups: the Java and Bali form. The distinct difference between the two strains is their size, with the Bali being much larger than the Java.〔 On the familial level, the family Dasyatidae is made up of 9 genera and 70 species. The genus of ''Neotrygon'' are called maskrays, because of the color pattern around their eyes.
