Sycozoa pulchra, (common name - stalked ascidian)[2] is a sea squirt in the family Holozoidae, first described by William Abbott Herdman in 1886 as Colella pulchra.[1][3] The taxonomic decision which determined the name, Sycozoa pulchra, and the species' synonymy was given by Patricia Kott in 1990.[1][4]

Description

This sea-squirt is composed of a cylindrical colony of paired rows of zooids on a stalk. It is usually transparent with white tipped siphons. The colony can grow to 6 cm, on a 30 cm stalk. They are seen more commonly in the cooler months when the colony heads regenerate.[2]

They are found in sediments, on reefs, in sea grass meadows and sponge gardens to depths of 25 m.[2]
