Styela canopus
Taxonomic Group: Tunicates


Styela canopus, commonly known as the Rough Sea Squirt, is widely distributed in temperate and tropical coastal waters. It was first described from the Red Sea in 1816, but its native region is thought to be the Indo-West Pacific. It has been documented in Europe, Africa, both sides of North America, Hawaii, Guam, the Caribbean, Brazil, Japan, Australia, and the tropical Indo-Pacific. It is found on ships, buoys, piers, docks, mangroves and coral reefs, but no economic or ecological impacts have been documented for this species.
