Diagnosis Hydroid colony forming massive, calcareous exoskeletons (= coenosteum) of varied shape; coenosteum with an internal complex network of coenosarcal tubes and covered externally by a thin ectodermal layer, coenosteal surface perforated by pores; margins of pores not elevated; large gastropores surrounded by smaller dactylopores, forming indistinct cyclosystems; polyps polymorphic; gastrozooids relatively short and stout, with an oral whorl of four to seven short capitate tentacles, arising from gastropores; dactylozooids long, slender, mouthless, with scattered capitate tentacles, arising from dactylopores; cnidome with stenoteles and macrobasic mastigophores; gonophores arising from coenosarc within chambers embedded entirely in the coenosteum.
Medusa free swimming eumedusoids with exumbrellar nematocyst patches, radial and circular canals present, without tentacles and sense organs; gonads occupying the place of an indistinct manubrium. [details]
