The octopus is one of the most amazing creatures in the world. How much do you know about the biology of octopus? Do you know that octopuses have 9 brains? Or that they die after birth?
Octopus is a cephalopod, and like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak. His mouth is at the center point of the eight limbs.
Octopuses have 9 brains. In addition to their central brain, they have a mini-brain on each of their arm. It allows each arm to act independently.
Another fun fact: octopuses have blue blood because they have adapted to cold and low oxygen water.
The male octopus dies soon after mating, but the female one has to live on to lay the eggs. They are not ready immediately. Female octopuses die around the time their eggs hatch. Octopuses that produce too few eggs will lose reproductive fitness.
