The Agoninae are a subfamily of marine fish from the family of armored lizards (Agonidae). The 15 species of Agoninae are found mainly in the northern hemisphere in the North Pacific and the North Atlantic. One species lives in the Gulf of California , one on the coasts of Argentina and the Falkland Islands .
features
Panzerropen of the subfamily Agoninae are 12.5 to 50 cm long. They differ from other subfamilies of the armored slugs in the non-enlarged rostral bone at the tip of the snout, a nasal bone that protrudes over the upper jaw, the lower mouth, the concave upper edge of the orbit and gill membranes that have grown together at the isthmus (throat). The lacrimal bone and nasal bone have contact with one another, but ethmoid and preventer , metapterygoid and entopterygoid do not. The free front end of the nasal bone is sawed or has a spike. The lower jaw is completely encompassed by the upper jaw when the mouth is closed. The back is never built high behind the dorsal fin. The representatives of this subfamily have three, more rarely four basal bones at the base of the pelvic fins, between which there are no pores. There is an epurale (an elongated, free-standing bone) in the tail fin skeleton.
