Botryllus schlosseri, commonly known as the golden star tunicate, is an invasive, colonial ascidian tunicate that grows on slow-moving, submerged objects, plants, and animals in nearshore saltwater environments.

Its range has spread over the last 100 years to a nearly worldwide extent. Ranging in the western Atlantic ocean from the Bay of Fundy to North Carolina, this is "the most common colonial tunicate in North America."[2] This species can be distinguished from Botrylloides sp. by the pattern of zooid growth. B. schlosseri zooids emanate from a center in the manner of the arms of a star. Also, there usually are fewer zooids per cluster (5-8 in B. schlosseri and 10 or more in Botrylloides).
