Introduction
Not surprisingly, the Cowtail Stingray's name refers to its unusual tail. The species is common in inshore tropical waters, venturing into estuaries and sometimes freshwater. They tend to be inquisitive and approach closely if fish have been speared.
Identification
The Cowtail Stingray has a disc that is slightly wider than long. It has small eyes and a very wide interorbital space. The tail is about twice the length of the disc. The upper surface of the disc is a uniform grey, brown or black. The lower surface is white. The tail is depressed basally becoming more cylindrical distally. The broad skin flap and tip of the tail are black.
Habitat
It can be found in muddy and sandy substrates in estuarine mangrove areas and inshore waters down to about 60 m in depth.
Distribution
The species occurs in tropical marine waters of the Indo-West Pacific. In Australia it is known from the central coast of Western Australia, around the tropical north of the country and south to the central coast of New South Wales .
