What is "bathydraconidae"

The Antarctic dragonfishes are a family, Bathydraconidae, of deep-sea perciform fishes.

They are benthopelagic fishes found in Antarctic waters. They are not fished commercially and little is known about them.

Molecular data support the split of bathydraconids into three clades: Bathydraconinae (Bathydraco, Prionodraco, Racovitzia), Gymnodraconinae (Gymnodraco, Psilodraco, Acanthodraco), and Cygnodraconinae (Cygnodraco, Gerlachea, Parachaenichthys).
