An octopus has three hearts, nine brains and blue blood
In our dark oceans live millions of unknown and mysterious animals and many wonderful underwater sea creatures.
However, the giant Pacific octopus is truly something strange. With three hearts, nine brains and blue blood, these eight-armed creatures are nothing short of extraordinary.
One main brain controls their nervous system with eight smaller brains controlling each of the eight arms. Two hearts pump blood to their gills, while one large heart circulates blood to other parts of the body.
They can also camouflage themselves for protection when hunting for food and by releasing a toxic dye when alarmed.
