Diagnosis Hydroids solitary, hydrocaulus long, hollow or more or less filled with parenchymatic gastrodermis, lower part of caulus with short papillae or/and longer anchoring filaments; tentacles arranged into two separate sets; oral tentacles composed either of one whorl of moniliform, one whorl of capitate tentacles, or several whorls of filiform tentacles; aboral tentacles arranged in one to three whorls of moniliform or filiform tentacles; gonophores borne above aboral tentacles, either directly issuing from hydranth wall or on blastostyles, gonophores develop into free medusae or fixed sporosacs.
Medusa with or without apical projection; manubrium usually not extending beyond umbrella margin, cylindrical or exceptionally with sac-like processes; mouth simple, circular; gonads undivided surrounding manubrium completely over its entire length, exceptionally also on sac-like processes of manubrium; one to four hollow, usually filiform tentacles, tentacles all uniform or differentiated into two types, differing in size and structure, tentacles exceptionally branched or rudimentary.
