caudal fin is joined to the long dorsal and anal fins in a small number of species but is separated in all the others. They have a protractable mouth and there is a rear facing spine on the opercle. They have between one and three complete or partial lateral lines. There are no teeth on the palatine and they may or may not be present on the vomerine bone. They grow to a maximum length of 40 centimetres (16 in).[2]
They lay eggs which are covered in hooks, some of which may develop into filaments. The eggs are clumped together in an egg mass the hooks on the eggs' surfaces interlocking with each other, which is most likely guarded by the male.[3]
