• Resumen

  • From 2013, the Pearl-oyster (Pinctada imbricata) have been more frequently observed in the Canary Islands. Most of the observations have been uploaded at the citizen science platform RedPromar (redpromar.org). There has been a total of thirty-three observation, most of them from the East coast of Tenerife Island. However, isolated individuals have also been observed in El Hierro Island and Lanzarote.

    Other observations have been directly registered by the authors of this study in Gran Canaria and La Palma Islands. This specie occurs from the intertidal habitat to the shallow waters, but at no more than 10 meters’ depth, and 2-4 cm in shell length.

    The presence, and more likely the establishment, of this specie in the Canary Island is important because it is a species originally distributed in the warm western Atlantic, North Caroline, West Indies, the Caribbean, Venezuela and Brasil (Cunha et al.

    2011). Therefore, the Canaries is a new location, off its normal distributional range.
