Here we report the first record of the red mouthed rock shell Stramonita haemastoma (Linnaeus, 1767) (Gastropoda, Muricidae) a predatory gastropod newly introduced to the English Channel. This species originally lives in the western Atlantic, eastern Pacific and Mediterranean Sea. Three specimens were collected on Pecten maximus at St-Martin-de-Bréhal, Normandy, France, on 2 February 2018. We present some hypotheses about the mode of introduction of S. haemastoma and its potential impact on the ecosystem in the English Channel. |
