Anarthropora monodon (Busk, 1860)


Anarthropora monodon is an encrusting bryozoan. Colonies have a somewhat branching or dendritic habit of growth. Autozooids are oval, flat or slightly convex, ranging in size from 0.6-0.7 by 0.3-0.4 mm.


Anarthropora monodon is rare in the UK. It is known from Shetland, Guernsey, the Aegean Sea, Norwegian waters and is not uncommon around the Faroe Isles. The species is little known and therefore rarely reported.


The species is able to colonise stones and shells and has been reported from waters between 50 – 1094 m on coarse grounds.
