Work from the early twentieth century on the hydromedusa Gonionemus veneris (Hargitt, 1897; Morgan, 1899) and the
scyphomedusae Rhizostoma pulmo (Hargitt, 1904) and Cassiopea xamachana (Cary, 1916) showed regeneration from various mutilated stages.
shelf ecosystem gelatinous zooplankton includes ctenophores, siphonophores, salps, hydromedusae, and
scyphomedusae. Potential impacts vary by ecosystem but can include significant predation on fish eggs, fish larvae, and heightened competition for zooplankton prey [11].
