This medium-sized species of Dasyatis is distinguished by the following characters: horizontal diameter of eye nearly equal to interorbital width and spiracle length; its tail is relatively short, less than two times disk width, distally filiform, with dorsal and ventral finfolds, ending approximately on same vertical line; height of dorsal finfold 1.5-2 in height of ventral finfold; the dorsal surface of disc is yellowish brown, with dark blotch between spiracles and two pairs of dark scapular and precaudal blotches; margins of disc and pelvic fins are blue dorsally; the ventral surface of disc white, with two symmetrical pairs of dark markings in adults (Ref. 36974).
Body shape (shape guide): other; Cross section: flattened.
一个 Dasyatis 的中等大小种几乎有水平的眼的直径等于眼间骨宽度与呼吸孔长度。 尾部相当短的, 少于两倍的圆盘宽度, 末梢部丝状, 有背部与腹部的被约略在相同的垂直联机终止的鳍褶; 腹鳍褶的高度的背部鳍褶 1.5-2 的高度。 体盘的背面土黄色, 与在呼吸孔与两对的深色肩胛与尾前椎斑块之间的黑色斑块。 背面的体盘边缘与腹鳍蓝色。 体盘的侧面白色, 有两对对称的深色斑纹当成鱼时。

Apparently associated with coral or sandstone reefs of the northeastern Brazilian continental shelf. Two female specimens were collected from the stomach of Rachycentron canadum (Ref. 36974). Juveniles also occurred in sandy beaches and estuaries. Ovoviviparous (Ref. 50449).
显然地伴随着珊瑚或巴西东北部大陆架的沙岩礁了。 稚鱼也出现在沙滩与河口。 卵胎生的.(参考文献 50449)

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205). A gravid female aborted one fully formed embryo (Ref. 36974).西南大西洋: 沿著巴西東北部海岸, 到巴伊亞州南部的從馬拉尼昂州。
