TheNortheasternAtlantic species Mycalemicracanthoxea Buizer & Van Soest , 1977 ( Porifera , Poecilosclerida ) in theStrait ofGibraltar ( Southern Spain )

The northeastern Atlantic species Mycale micracanthoxea Buizer & Van Soest, 1977 is a componentof subtidalshallow water and brackishwater harbour poles and pontoons from The Netherlands, where it grows attached to shells, barnacles, etc. It was found in similar zonesand habitats ofAlgeciras Bay (Gibraltar Strait, southern Spain) and Isla Cristina (Huelva, southern Spain) where it is very common. This new record constitutes the southernmost limit of the geographical range of this species. This article presents some data on the anatomical variability ofMycale micracanthoxea, along with a discussion on the possible causes of its observed distribution.
