Pateobatis bleekeri is a species of ray from the family of sting rays(Dasyatidae). The specific epithet honors the Dutch ichthyologist Pieter Bleeker .

features

This ray can reach a diameter of up to 105 cm. The underside of the body disc has a wide, dark border. The tail is conspicuous, being several times as long as the disc, and has spines.

Way of life

Pateobatis bleekeri lives in tropical biotopes in the Indo-Pacific region between Pakistan and the Malay archipelago . The species is ground-dwelling on the border between fresh and brackish water, so it can be found, for example, in estuaries and other soft soils from the surf zone down to depths of around 30 meters. Ground-dwelling invertebrates serve as food.

The ovoviviparous species is able to double its population within 4.5 to 14 years, which means a low resistance to population changes, for example through fishing.

Economically, the species is of very little importance. The meat can be eaten and the skin used to make leather.

Systematics

The ray species was described in 1860 by the English zoologist Edward Blyth under the scientific name Trygon bleekeri and later assigned to the genus Himantura . When the Dasyatidae was revised in mid-2016 , the species was placed in the newly introduced genus Fontitrygon .
