Abstract

First record of the gastropod Stramonita haemastoma (Linnaeus, 1767) in the English Channel

Highlights

  • Species of the oyster drill Stramonita haemastoma complex are widespread in warm-temperate and tropical latitudes of the western Atlantic and eastern Pacific Oceans, as well as in the eastern Mediterranean Sea (Butler 1985; Claremont et al 2011)

  • We identified the snails as S. haemastoma, a member of the S. haemastoma complex that consists of six subspecies

  • Stramonita haemastoma is a typical representative of the gastropod family Muricidae with a medium-sized solid shell that commonly reaches between 70–80 mm in size with a prominent pointed spire and a nearly straight columella

Summary

Introduction

Species of the oyster drill Stramonita haemastoma complex (several subspecies are recognised) are widespread in warm-temperate and tropical latitudes of the western Atlantic and eastern Pacific Oceans, as well as in the eastern Mediterranean Sea (Butler 1985; Claremont et al 2011). Named the red mouthed rock shell, Stramonita haemastoma has a large protoconch, a character typical for gastropods with a long pelagic larval duration (Claremont et al 2011; Scheltema 1971; Richter and Thorson 1975). They are predatory snails (Clench 1947) commonly found in the intertidal zone of rocky shores, preferentially in the midlittoral (Ramírez et al 2009) and subtidal (Rilov et al 2001). Stramonita haemastoma is potentially the only amphi-Atlantic species, in the complex and the one with the broadest range, including the eastern Atlantic the continental coastline of the Mediterranean and West
