Description

The smalleye smooth-hound is a small houndshark from the western Atlantic, ranging from the northern coast of Venezuela to Brazil. The species grows to about 77 cm and has a slender, grey body with flat, plate-like teeth with which it crushes hard-shelled prey. As a bottom-dweller the fish lives on mud, sand and calcareous bottoms of coastal water and tolerates brackish water. It feeds mainly on crustaceans. The species is viviparous with a yolk-sac placenta and bears 1 to 7 young. Because of heavy fishing it is listed as Endangered (EN) on the IUCN Red List.
