Eight invertebrate species, rediscovered, demographically expanding or newly observed are reported from the Pertuis Charentais Sea. They were sampled from intertidal rocky shores (Alpheus macrocheles, Aslia lefevrei, Epitonium clathrulatum and Haliotis tuberculata), intertidal sand flats (Africorchestia spinifera and Arcuatula senhousia) and subtidal bottoms (Aslia lefevrei and Rapana venosa). One species is pelagic (Lepas anatifera). Most of them are within their natural range. However, R. venosa, native to Southeast Asia, has been introduced in the Pertuis Charentais since the 2010s and its populations are currently expanding. The new northern limit of Africorchestia spinifera along the Atlantic coast is defined as the Ré Island. Phoresis of Crepidula fornicata on Carcinus maenas is noted but was already described in European waters whereas it is a hitherto undescribed and unexpected association with the gastropod R. venosa.Read less <
