Enteroctopus dofleini (Wülker, 1910) - When threatened, Giant Pacific Octopus shoot out an inky substance that creates an instant smokescreen. Sometimes the ink cloud takes the actual shape of an octopus, providing a diversion that allows the real octopus to escape from predators.

With no skeleton to get in its way, Giant Pacific Octopuses can also squeeze their bodies into incredibly small spaces – any space larger than its powerful beak is fair game.

Giant Pacific Octopuses are terminal spawners, meaning females only have one opportunity to reproduce. They typically mate closer to the end of their fairly short lifespan, which on average is only five years. Luckily, octopuses lay anywhere from 18,000 – 74,000 eggs, helping to strengthen the vitality of the species. While waiting for her eggs to hatch, the mother remains with the eggs and does not eat, staying to protect her babies at all times. Octopuses typically die shortly after her babies hatch.
