The bryozoan Schizoporella errata was found in the waters of the island of São Miguel (Azores, Portugal) in August 2013. Its occurrence in the Ponta Delgada Marina suggested that it had been newly introduced into the area, probably via maritime traffic, owing to the fouling proclivity of these cheilostome colonies. It may be expected that S. errata will disperse throughout the Azores Archipelago, being transported by recreational boating as a fouling component of hulls. Measures to minimize a rapid spread of the species should be addressed and the effects of its presence on the native community studied.
