Resumo(s)

The tropical brown-striped octopus (Amphioctopus burryi) is recorded for the first time from Madeira Island. Its identification was confirmed through morphological analysis and DNA barcoding molecular techniques. By also analysing specimens from the Canary Islands and Cabo Verde Islands, we provide evidence supporting the amphi-Atlantic distribution of this species. Furthermore, we discuss the potential role of ongoing ocean warming in the expansion of A. burryi in the Canary Islands and its recent record in Madeira Island.
