From: First insights into the spatial behaviour of Octopus vulgaris in the wild using acoustic telemetry
Total activity space areas (based on centres of activity) for the four Octopus vulgaris with the highest residency indices. Yellow dots represent the acoustic telemetry receiver locations and the shaded colour areas represent the activity space (KUD = kernel utilisation distribution). Blue dots show the diving area where specimens 24 and 26 were captured and released by scuba divers, while specimens 19 and 21 were captured by fishery traps
