Ecology
Sessile; depth range 0 - 15 m (Ref. 113256). Tropical, preferred 17°C (Ref. 107945)
Eastern Atlantic, Indo-West Pacific, and the Antarctic: Equatorial west coasts of South America and west and southeast Africa. tropical to temperate.
Length at first maturity / Size / Weight / Age
Maturity: Lm ?  range ? - ? cm Max length : 40.0 cm TL male/unsexed; (Ref. 101433)
This is the largest African pyurid, some specimens are larger than 10 cm across (Ref. 2673). Benthic, marine; aggregations on sediment free rocky substrate; solitary on sandy substrate (Ref. 1134). It forms aggregates or mats in rocky intertidal environments (Ref. 3464). Also found in pier piles and reefs. Feeds on plankton or particles (Ref. 101296).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Members of the class Ascidiacea are hermaphroditic; both cross- and self-fertilization is typical. Life cycle: Eggs develop into lecithotrophic larva before metamorphosing into benthic adults.
