Electrophoretic variability ofAlcyonidium mytiliDalyell, 1847 (Bryozoa, Ctenostomida) from European coasts

Abstract
An electrophoretic study using polyacrylamide gradient gels and isoelectric focusing has confirmed that the ctenostome bryozoan Alcyonidium mytili Dalyell, 1847, to date considered a valid species, in fact comprises a number of cryptic species, of which three are present on the French, Danish, and Swedish coasts.
