There are two suprabranchial organs in its head. Its gas bladder belongs to physoclistaus and it extends to caudal peduncle. The verge of placoid scale is black and its body black net-like. Its stomach is strong and the intestine has a long length with two pyloric caecas. The lateral line scale formula is 3638(7/15 - 16).
