Rhacostoma atlanticum is a species of aequoreid hydrozoans. The species has been reported from the Atlantic coastline of the North America, Colombia, West and Central Africa.Polyp stage is unknown.
The medusae reach up to 30–40 cm (12–16 in) in diameter with the bell height 3–4 times less than the width. Specimens found in the northern waters tend to be transparent, while those found farther south are tinted pink. The broad stomach gives rise to 80–100 non-branching radial canals.Tentacles are slightly more numerous than radial canals and do possess elongated conical bulbs.
