9 brains, 3 hearts,blue blood: Some wild facts about octopuses

Описание: Each octopus also contains one central brain that functions as a process and 8 individual brains that function as preprocessors on each tentacle. 2/3rds of all of the neurons in an octopus are contained in the tentacles. This gives the octopus amazing abilities of sensing through feeling.

Backing all this unusual anatomy up even further, octopodes blood is blue. Their blood contains a copper based chemical called cyanoglobin, as opposed to humans hemoglobin. They function to help carry oxygen, but cyanoglobin is slightly less effective and also makes their blood blue. Because of this lower efficiency, you won’t see octopuses running marathons anytime soon.
