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.
一個 Dasyatis 的中等大小種幾乎有水平的眼的直徑等於眼間骨寬度與呼吸孔長度。 尾部相當短的, 少於兩倍的圓盤寬度, 末梢部絲狀, 有背部與腹部的被約略在相同的垂直線上終止的鰭褶; 腹鰭褶的高度的背部鰭褶 1.5-2 的高度。 體盤的背面土黃色, 與在呼吸孔與兩對的深色肩胛與尾前椎斑塊之間的黑色斑塊。 背面的體盤邊緣與腹鰭藍色。 體盤的側面白色, 有兩對對稱的深色斑紋當成魚時。

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).
顯然地伴隨著珊瑚或巴西東北部大陸棚的沙岩礁了。 稚魚也出現在沙灘與河口。 卵胎生的.(參考文獻 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。
