With a hard beak hiding among your eight powerful arms, and a venom gland just behind it, you can pull in even the biggest prey, kill them, then eat them.
You are a complex organism, with one of the biggest brain-to-body ratios outside the vertebrate animals. You’re clever, with problem solving capabilities, and a body that has almost no hard parts at all, meaning you can hide in any crevice, and “leap” out on passing prey. Scientists have found that you can solve problems such as mazes, and remember solutions you have found. It has even been observed that you are the closest thing to an alien life form without actually leaving the planet.
There are many thousands of different species of Octopus, in every ocean, at every depth from the surface to five miles down. You’re amazing.
