Rhodaliidae is a family of
siphonophores. In
Japanese they are called ヒノマルクラゲ (hinomarukurage).[5]
Rhodaliids have a characteristic gas-secreting structure called
aurophore.[2] Below the enlarged
pneumatophore (float), the
siphosome and
nectosome are contracted into a complex.[2] Rhodaliids have a
benthic lifestyle and use their
tentacles to attach themselves to the seafloor.[2]
