Abyssochrysos is a genus of bathyal sea snails, marine gastropod mollusks in the family Abyssochrysidae.

Description

The characteristics (shell, radula and anatomy) of the species mark this genus as simple gastropods, unassigned in the clade Caenogastropoda. Their taenioglossate radula (formula: 2+1+1+1+2) is unique among the Prosobranchia because of the sickle-shaped rachidian tooth and the thick, sinuous, sharply cusped lateral teeth. They have tentacles but lack eyes. The mantle cavity goes deep (about 2½ whorls). The long, wide ctenidium is monopectinate. The pallial gonoducts are closed. The large penis-like organ is a right-dorsal mantle process.
