Using octopuses, which have the largest invertebrate brains and sophisticated eyes, we experimentally verified the senses that animals use when recognizing objects. As a result, it was revealed that the giraffe octopus that inhabits the coast of the Ryukyu Islands perceives crabs, which they feed on, through a combination of sight and touch, and that sight is prioritized over touch for prey recognition. clarified important matters.
