Telatrygon zugei is a stingray species and lives in the northern Indo-Pacific on coasts and in river mouths between India , Indonesia (east to Java ) and southern Japan .
features
Telatrygon zugei reaches a total length of a maximum of 75 cm with a pane width of up to 29 cm. It has a diamond-shaped pectoral fin disc that tapers long and pointed towards the muzzle. The tail is whip-like, significantly longer than the disc and has a poison sting. The top is chocolate brown, darker towards the tail; the underside is white with a light brown border.
Way of life
The ray lives close to the ground, mostly over sandy ground on coasts at depths of up to 100 m and in river mouths. There he prefers to hunt small crustaceans , mainly shrimp , but also smaller fish. It is ovoviviparous with litters of one to four young animals, the disc widths of seven to ten centimeters. In the uterus, the embryos first feed on the egg yolk, then on a slimy fluid that is secreted from the uterus and enriched with fat and proteins. It is often brought in as by-catch and its meat is used. Because of the heavy fishing of its habitat, it is now considered to be at low risk .
Systematics
The ray species was described in 1841 by the German natural scientists Johannes Müller and Jakob Henle under the scientific name Trygon zugei , later assigned to the genus Dasyatis . When the Dasyatidae was revised in mid-2016 , the species was placed in the newly introduced genus Telatrygon .
