Atorella octogonos is a species of crown jellyfish in the family Atorellidae.
The specific epithet is derived from the Ancient Greek words októ ("eight") and gónos ("reproductive organ"), in reference to the eight gonads of the species.
The outer bell has several nematocyst warts, each around 0.1 millimetres (0.0039 in) in diameter.
It has six tentacles, each of which end in a head of nematocysts.
It has eight spindle-shaped gonads, which are a cream-tan color; the species is otherwise transparent and colorless.
