An octopus has three hearts, nine brains, and blue blood
Our dark oceans are home to millions of known and mysterious specifies, the many wonders of underwater sea-creatures. However, the giant Pacific octopus is truly something magnificent. 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 their eight arms. Two hearts pump blood to their gills with one larger heart circulating blood to the rest of the body. They can also camouflage for protection when hunting for food and release a toxic ink when alarmed. Fascinating, right?
