Facts
- Colonial tunicate; settlement of larvae (tadpoles) within a few hours after liberation; total length tadpole 1.8 mm; after tail resorption upon settlement 0.3 mm; functional ascian in 4 d after settlement (Ref: Yama1975)
- Asexual reproduction till space becomes limiting, then sexual reproduction; Parent colonies regressed and degenerated after liberation of larvae. (Ref: Yama1975)
- Hermaphroditic; external fertilisation (Ref: Wiki)
