Description

Ascidia mentula is a solitary ascidian of about 5 to 18 cm in length, occasionnaly up to 30 cm. The test is smooth, cartilaginous and thick and it is generally pink. The body is ovoid and is attached to the substratum by the left side. The oral siphon is broad, terminal, eight-lobed and may have eight white markings. The atrial siphon is one-half of body length from the oral siphon. The pink sea-squirt lives attached to rocks, wrecks or shells. This species has a rather long lifespan, some of them living up to 7 years old.

Distribution

Ascidia mentula is found from 5 m to depths of 200 m in the Atlantic Ocean from Norway to the Mediterranean Sea, in the North Sea and the English Channel.
