An invertebrate is an animal without a backbone. This invertebrate protects itself in an awesome way. I wouldn't have thought of this myself. Octopuses spray a cloud of ink at their predators. Some of the octopus' body characteristics are very different from us mammals.
Octopuses have a mouth underneath their tentacles.
Their eyes are under their huge brains. They have eight tentacles that help them capture and dissect their prey. They can also grow to be about twenty feet wide, thirty-one feet across, and weigh one hundred to six hundred pounds. Octopuses like four different kinds of seafood. They find these in the Pacific Ocean where they live.
