Comprehensive Description

Read full entry
This compound tunicate (many individuals are embedded in a common tunic) grows in a globular (sometimes flat) mass with a short, narrow attachment stalk. The colonies are not encrusted with sand. The pharynx of individuals has 4 rows of stigmata. Colored from pale orange to yellow to pink to dark purplish-red or brown. Most colonies are less than 2 cm in diameter, though they can be larger as here (up to 10 cm). Each of the closely packed zooids has its own incurrent siphon and pharynx, but several adjacent zooids share a slightly raised common buccal or excurrent siphon and atrial cavity.
