Shorter nostrils, no enlarged tubercles on the tip of the snout. Olive gray, reddish brown or chocolate brown. Pale translucent area on either side of rostral ridges. Darker brown spots or blotches on sides. Lower surface pale yellowish, greyish or dusky white, tip of the snout with a more or less conspicuous sooty blotch (Ref. 6902).
Body shape (shape guide): elongated.
Found on shallow, soft bottoms. Ovoviviparous (Ref. 50449). Flesh considered low quality (Ref. 5217). Traded as an aquarium fish at Ceará, Brazil (Ref. 49392).
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).
