Diagnosis Hydroids solitary or colonial; hydranths stolonal, branched, or rarely sessile, arising from creeping hydrorhiza; erect colonies monopodial with terminal hydranths, stems monosiphonic or polysiphonic; perisarc terminating either at base of hydranths or forming a pseudohydrotheca; hydranths with one or more whorls of filiform distal tentacles, tentacles confined to narrow zone below hypostome; gonophores free medusae or fixed sporosacs developing either on hydrocauli, stolons, or blastostyles.
Medusae bell-shaped; mouth circular, with simple or dichotomously branched oral tentacles inserted distinctly above mouth rim, ending in nematocyst clusters; four radial canals and circular canal; marginal tentacles solid, contractile, either solitary or in clusters, borne on 4, 8, or 16 tentacular bulbs; gonads on manubrium, either forming a continuous ring or in adradial, interradial, or perradial position; adaxial ocelli absent or present.
