Hey, guys! It's Otto, and today I want to teach you about the octopus. First off, let's start with their size. The smallest octopus around is smaller than an inch long, and the biggest - the Giant Pacific Octopus - can grow to about 16 feet long! They live all over the world, from the ocean's surface to its floor, and they like to feed on things like clams and crabs.
