Reproductive Biology

Fertilized eggs are kept within a brood pouch made by broad, leaf-like thoracic appendages. Newly hatched juveniles look very much like their parents. Females catch gelatinous zooplankton like salps and pyrosomes and eat out the insides, climb inside, fashion the tunic into a barrel, and use it as a brood chamber. The female grabs newly hatched young and puts them into the inner wall of the barrel. While attached as a group, the female catches prey and shares it with her brood.The young also eat the barrel material. The barrel slowly is eaten and decomposes so that the young swim away to live solitary lives. No one knows how or when the males and females get together for fertilization of the eggs. Males are not known to make barrels.
