Environment: milieu / climate zone / depth range / distribution range
Ecology
Sessile; depth range 2 - 24 m (Ref. 102216). Tropical
Indo-West Pacific.
Length at first maturity / Size / Weight / Age
Maturity: Lm ? range ? - ? cm Max length : 20.0 cm H male/unsexed; (Ref. 82063)
Height may be over 20 cm (Ref. 82063). Depth range is based on occurrence. Maximum depth from Ref. 102328; to be replaced with a better reference. It is found in coral reefs, attached to the fringes of big coral boulders in both clean and muddy water. It can tolerate silted environments (Ref. 82063). Filter-feeder (Ref. 68823).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Demospongiae are hermaphroditic. Life cycle: The zygote develops into parenchymella larva (free-swimming) before settling down on a substrate where it grows into a young sponge.
