Distribution and Habitat
Distribution in Britain & IrelandRecorded in a few locations on the west coast of Scotland (but probably more widespread (P. Hayward, pers. comm.)) and the north east of England. It is more common around the coast of Wales and along the south coast of Britain.
Global distributionPresent in the Kattegat and shores of the southern North Sea. Recently recorded in the western Mediterranean.
Biogeographic rangeNot researched Depth rangeIntertidal to at least 42m
Migratory   
Distribution Additional InformationThe distribution may be imprecise since Conopeum reticulum is frequently confused with other species but it is probably common off all British coasts (Hayward & Ryland, 1998). Conopeum reticulum has been reported from a wide variety of hard substrata including boulders, cobbles, shell and small stones on sediment, as well as the shells of %Mytilus edulis%. Colonies inhabiting stones and cobbles are probably ephemeral, removed by abrasion and rolling during winter storms. Grant & Hayward (1985) reported Conopeum reticulum in shallow water bryozoan assemblages in the English Channel at a mean depth of 42m.
