Anthomedusae

Anthomedusae is a suborder of cnidarians, specifically within the class Hydrozoa. These organisms are characterized by their hydranths and reproductive zooids, which are not protected by thecae. Some Anthomedusae have medusae that bear gonads in the manubrium and lack lithocysts. In the broader classification of cnidarians, Anthomedusae are part of the order Hydroida, which typically exhibits colonial and polymorphic forms. The medusae in this suborder are bell-shaped, with gonads located on the stomach or sides of the manubrium, and possess pigmented eyespots. Unlike some other hydrozoans, their polyps lack a protective cup called a hydrotheca.12
