Description
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 further 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 possess elongated conical bulbs.
