Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 5.0 cm TL male/unsexed; (Ref. 26875)
Thallus sac-like, clavate, often filled with water, much attenuated below as a slender, usually simple stipe of about 1 cm long. Tends to form colonies. Thalli arises from a common basal crust (Ref. 26875).
Found in the intertidal and upper infra-littoral zones (Ref. 26875).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Only plurilocular sporocysts have been observed in the wild. Develops from surface cells which after growing into cylindrical filaments, divide once or twice longitudinally and 5 to 7 times transversely. Paraphyses are wanting. Unilocular sporocysts have not been found, thus, a complete life cycle is unknown (Ref. 26875).
