Perophora viridis is a colonial sea squirt with the individual zooids united by a stolon or stem but spaced widely apart.

The muscles extend for about a quarter of the length of the zooid and their function is to enable the animal to contract and protect its siphons.

[2] Perophora viridis is found in the tropical western Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico.

[1] In the Caribbean it is plentiful in nutrient-rich lagoons where the creeping stolon spreads like a vine across the seabed, over seaweed and oysters and around mangrove roots.

[3] The stolons of tunicate and bryozoan run parallel with and round each other, making the whole resemble a single organism.

It draws water in through the buccal siphon and food particles such as bacteria and zooplankton get trapped in a mucus net that lines the pharynx.
