Scolionema suvaense is a small coronate scyphozoan jellyfish (order Coronatae, family Linuchidae) found in shallow tropical coastal waters of the Indo-Pacific, with a distinctive bell bearing a prominent coronal groove—a diagnostic feature of coronate medusae representing the most ancestral order of Scyphozoa. The species forms small medusae that inhabit mangrove channels, lagoons, and nearshore tropical waters. Its biology highlights the ecological diversity of the ancestral scyphozoan body plan. Genomic data have been generated for this species and are available in public databases, enabling comparative studies of cnidarian evolution and ecology.
