Bugula turbinata is an erect bryozoan, found in the southern part of Britain. The colonies are composed of dichotomous branches arranged spirally around the main axis to form bushy tufts. The species is orange-brown in colour and is typically 3 – 6 cm high. Autozooids are rectangular, sometime narrowing at the proximal end, closest to the colony origin.
The species is able to colonise hard substrates and is characteristically found on the underside of boulders and in gullies near the low water mark. It is the only British Bugula species that is really characteristic of the shore, but it can also be found in shallow subtidal waters on stones and shells.
Bugula turbinata is found in the south of Britain, extending north to the Clyde Sea on the west coast and Northumberland on the east.
