Rhodaliids have a characteristic gas-secreting structure called aurophore. Below the enlarged pneumatophore (float), the siphosome and nectosome are contracted into a complex. Rhodaliids have a benthic lifestyle and use their tentacles to attach themselves to the seafloor.
Genera and species Rhodaliidae contains the following subtaxa: Angelopsis Fewkes, 1886 Angelopsis euryale Pugh, 1983 Angelopsis globosa Fewkes, 1886 Arancialia Hissmann, 2005 Arancialia captonia Hissmann, 2005 Archangelopsis Lens & van Riemsdijk, 1908 Archangelopsis jagoa Hissmann, Schauer & Pugh, 1995 Archangelopsis typica Lens & van Riemsdijk, 1908 Dendrogramma Just, Kristensen & Olesen, 2014 Dendrogramma enigmatica Just, Kristensen & Olesen, 2014 Dromalia Bigelow, 1911 Dromalia alexandri Bigelow, 1911 Rhodalia Haeckel, 1888 Rhodalia miranda Haeckel, 1888 Steleophysema Moser, 1924 Steleophysema aurophora Moser, 1924 Stephalia Haeckel, 1888 Stephalia bathyphysa (Haeckel, 1888) Stephalia corona Haeckel, 1888 Stephalia dilata (Bigelow, 1911) Thermopalia Pugh, 1983 Thermopalia taraxaca Pugh, 1983 Tridensa Hissmann, 2005 Tridensa rotunda Hissmann, 2005 Tridensa sulawensis Hissmann, 2005
