Temachia microstoma

Temachia microstoma is an encrusting bryozoan. Colonies are composed of a single layer of autozooids and form patches which often have an irregular outline. Autozooids are oval, hexagonal or irregular in outline and strongly convex. They range in size from 0.6-0.9 by 0.5-0.7 mm and have no spines.

Temachia microstoma has been recorded from Shetland and the northern Bay of Biscay, but very little is known about its distribution since the species has often been confused with a superficially similar species of Escharella.

The species is able to colonise hard substrates from offshore waters.
