The answer to your question "what does the beak of an octopus do" is... The beak of an octopus helps it to eat. The tentacles help grab the food and then they put the food into it's beak. Don't ever touch the beak of an octopus. i is very sharp and can hurt you. (if it is still on an octopus)
It will consume (eat) like most other lifeforms on Earth. well if an octopus is hungry it will do the same thing a human will do eat specifically it will eat other fish the only difference is that a human can shop for food dah..........................
If you're referring to Morticia Addams, the character created by cartoonist Charles Addams, no, she was a human. However, her famous dress was black, skintight and the zigzag hemline resembled octopus tentacles!
Blue Ringed octopus, Day octopus, and Giant octopus. Blue ringed octopuses are small sized, but have deadly toxic that can kill a fully-grown man. Day octopuses are large and can float to attack divers. Giant octopuses are the largest species that can kill a human with a beak bite.
Octopus move through water by a foot. The foot extends from either the mouth or the stomach. The foot takes them around to where they want to be. The only difference is that this foot is nothing like a human foot.
