General Description

Colonies of zooids that are usually arranged in parallel rows. The rows of zooids are grouped into pod-like structures, each pod with a communal siphon or opening in the centre. Generally coloured white with patterns of yellow, brown or purple. Colony up to 30 cm wide, zooids 1-2 mm long.


On some reefs, these ascidians form flat sheets of zooids rather than the pod-shaped colonies with a central opening.


Worldwide. Southern and eastern Australia.


Reef areas, to depth of 20 m.
