Environment / Climate / Range
Demersal; depth range 1 - 10 m (Ref. 3086). Tropical
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
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).
