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

[2] 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.

The mantle cavity goes deep (about 2½ whorls).

The large penis-like organ is a right-dorsal mantle process.
