Climate / Range
Complementary nematocysts microbasic euryteles, having a much ornamented shaft; male blastostyles completely reduced, with distinct neck connecting gonophore chambers; female blastostyles fully reduced, spadix unbranched during early ontogeny, shed when mature; eggs with thin pellicle, placed along axis of blastostyle (Ref. 3086).
Maximum depth from Ref. 3100. Occurs in shallow waters from 1 to 10 m in depth, on rocks and barnacles (Ref. 3086 and 3100). It prefers shaded microhabitats and current flows, where it can form extensive meadows (Ref. 3101). 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).
