Hydrozoa | Anthoathecata
Environment: milieu / climate zone / depth range / distribution range
Benthic; depth range 0 - 30 m (Ref. 3086). Subtropical
Indo-Pacific, Northeast Atlantic and Mediterranean.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 15.0 cm H male/unsexed; (Ref. 3669)
Complementary nematocysts atrichous isorhizas, cnidophores present in some hydranths; male and female blastostyles reduced; spadix of female blastostyle bifurcated when immature; mature eggs scattered over main axis of blastostyle (Ref. 3086).
Occurs from depths of 0 to 30 m, on rocks, concretions, barnacles, mussels, and algae (Ref. 3086). Members of the order Anthoathecata are mostly colonial A-form hydroids. Life cycle: The zygote develops into planula inside the gonophore and is later released as an actinula which metamorphoses into polyp stage (Ref. 833).
