Escharella klugei is a flat encrusting bryozoan. Colonies form rounded patches, composed of a single layer of autozooids. Autozooids are oval to hexagonal and strongly convex. They are 0.6-0.8 by 0.4-0.5 mm, with four spines present.
Escharella klugei is a boreal-arctic species that has been reported from Greenland, the Barents Sea, the White Sea, Svalbard and Bergen Fjord in west Norway. It occurs commonly around the Faroe Isles. In the British Isles, it is known from Rockall Bank.
The species is able to colonise hard substrates in subtidal waters. It ranges from shallow waters to depths beyond 200 m (Kuklinski 2009).
