Lycodinae eelpouts have elongate heads and bodies, they have between 58 and 144 vertebrae. The
branchiostegal membranes are typically attached to the isthmus, although not in
Lycodapus. Most have a wide bill slit but in some species it is more restricted. They do not usually possess a pore between the eyes. There are between 4 and 9 suborbital bones, typically, from 6 to 8, and these create an L-shaped pattern around the eyes. There are between 6 and 12 fin rays in the
caudal fin. They have no spines in their fins, although in a few species there are
pelvic fin rays which are fused into a pelvic splint. ==Distribution==
