Thick-skinned jellyfish (Trachymedusae) [Trachymedusae]

Description

Trachymedusae are jellyfish with a more robust, often textured bell compared to some other groups. Divers may encounter them as slow, graceful swimmers with subtle patterns and a firm-looking silhouette. They’re usually seen in open water or along current lines, where they drift and pulse with the flow.
