Giant pacific octopus

The giant pacific octopus has some amazing features. It even has jet propulsion. Here's how it works: you see, you know that hole around the octopus's head? Well that's where they suck in some water then push it out another tube, boosting them 25 mph. Although they usually just crawl along the floor. And guess what? If a predator bites off one of its arms, it'll grow back. You know the ink? You know, that's poisonous! But don't worry - if you're diving with one, the suits will protect you, and I don't think it works on humans. And it has camouflage, I mean any, any, ANY color! Although polka dots are not included. I mean, who would need polka dots in the sea? And these octopuses can be pretty big - about as big as a firetruck.
