Rhodaliidae

Rhodaliidae is a family of siphonophores. In Japanese they are called ヒノマルクラゲ (hinomarukurage).

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.
