Escharoides jacksoni

Escharoides jacksoni is an encrusting bryozoan. The colonies form large thick crusts composed of a single layer of autozooids. Autozooids are hexagonal, rhombic or oval, with three to five short spines. Autozooids are large approximately 0.8-1.0 by 0.8 mm and visible to the unaided eye.

Escharoides jacksoni is essentially a circumpolar Arctic species. It has been recorded from Greenland, the Faroe Isles and the northern Bay of Biscay. It possibly ranges along the western edge of the continental shelf into the British sea area.

The species is able to colonise shells, stones, Lophelia coral, calcareous bryozoans and hydrocorallines. It is a deep water species ranging from 50 m to approximately 1500 m.
