Projecting future climate change impacts on the distribution of the ‘Octopus vulgaris species complex’
IntroductionHistorically considered to be a single cosmopolitan species, the so called Octopus vulgaris species complex (OVSC) is now recognized to be a group of (at least) six cryptic species: O. americanus (in the west Atlantic), O. vulgaris (in the northeast Atlantic and Mediterranean Sea), O. af...
