Brazilian large-eyed stingray

Dasyatis marianae is a Stechrochenart and lives only off the coast of Northeast Brazil.

Features

Dasyatis marianae has a diamond-shaped pectoral fin disk, which is about as wide as long, and widths up to 40 cm reached. Laterally, the disc is rounded, the front sides are slightly concave and the muzzle does not protrude far out. The eyes are large, followed by approximately equal spray holes. The tail is one and a half times as long as the disc wide, tapering towards the tip and carries up a sting. The coloring of the disc top is golden brown with dark brown spots and a narrow blue border followed by a brown ribbon. The underside is white, darker towards the edges and wearing a pair of kidney-shaped, dark brown spots next to the gill slits and backwards subsequent brighter spot pairs. The tail is dark brown above and white below with lateral blue stripes, the top of dark red.

Way of life

The Rays lives along the northeast coast of Brazil between Maranhão and Bahia in coral and sandstone reefs at depths 2-15 m. Young animals live also near the beach and estuaries. He is ovoviviparous with litters of a single pup that is born with a slice width of 13 cm to 14 cm in June or November-December in shallow water.

For humans it is safe and shows divers over cautious. Often it is introduced in small quantities by local inshore fishermen and captured partly also for sale as an ornamental fish. The impact of fishing on the stock figures is not known. Threatened he is by human impacts on the reefs of its habitat, in contrast to him but also several Brazilian marine protected areas are - such as the Parque Estadual do Parcel Manuel Luiz in the north and the Parque Nacional Marinho dos Abrolho in the south - as a retreat available. Since too little information available to the stock and catch data, the conservation status by IUCN is evaluated with DD (data deficit ).
