Today,while watching the BBC life series I was mesmerized by many aspects of nature, but what stuck with me most was that a female octopus lays many many eggs (approximately 100 000) tends to them for six months. Caressing them, and just making sure the eggs are protected. During that time she doesn’t leave her den, Not once, so she doesn’t hunt for food which holds vital energy for her survival. During her pregnancy she thus, slowly starves herself to give the eggs a chance. On her last energy she apparently blows water over them to help them hatch and then she dies.
This sacrifice makes them (to me) one of the most devoted mothers in nature.
Oh and they also have 3 hearts and blue blood.
