简单描述
型态特徵 | 形态测量图
Elongate, with a heart-shaped disk terminating in a wedge-shaped snout with a few enlarged tubercles on tip (Ref. 26938). Ashy gray to olive brown or chocolate brown. Entire upper surface is thickly freckled with several hundred small whitish dots. Lower surface is pale yellow or yellowish white or plain white, fins slightly darker than trunk (Ref. 6902).

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).西大西洋: 美國北卡羅萊那州到墨西哥灣北部與墨西哥的尤卡坦半島。
