The North Pacific giant octopus is the world's largest octopus. It's almost as big as a car, with an arm span exceeding 4 meters. North Pacific giant octopus hug massive crab, such as snow crabs, to paralyze them instantly. Then they use their suckers to crush their prey to pieces before enjoying the feast. The octopus's large body also plays a crucial role in raising young. Mothers lay eggs, then fast for 10 months to cover and protect their offspring from predators. Once the eggs hatch, the mothers die. It's a moving story of sacrifice.
