Styela angularis (angular sea squirt) is a solitary, hermaphroditic ascidian tunicate that is found along the coast of Southern Africa from Lüderitz Bay in Namibia to the Eastern Cape.[2]

Description

Order of 100 millimetres (3.9 in) tall, with a tough flexible opaque hexagonal test tapering down to a narrow base peduncle. Stands upright on the substrate. Cloacal siphon terminal, and oral siphon slightly ventral and posterior.

Behaviour

Occurs singly on rocks or other hard surfaces where water is clean and fairly fast moving. Often covered by epibionts.
