General Description

Rounded body with two openings (siphons) that project upward or sideways. Each individual often supports a variety of epiphytic organisms growing on the surface, giving a green-brown appearance. Up to 35 cm high.

Biology

These ascidians (sea squirts) often live in small groups on rocky areas. Their scientific name is derived from the stolons that extend from the base of the animal to secure it to the rocks. While they often appear green-brown because of encrusting overgrowth, their bodies are actually orange or pink.

Distribution

Southern temperate oceans.

Habitat

Pier piles, rocky shores and reefs, to depth of 15 m.
