yes they do.mostly people who live by sea.and they eat them too.
You could, but not a whole lot of people do.
Although it may seem like a bad idea to some people, it is ok to eat the ink of an octopus. Not alone however. You should it with some form of meat.
No because the octopus will squirt it's ink at the shark and the shark cant see so it doesn't eat the octopus.
It uses its funnel to shoot ink when it is in danger. Some octopi have special ink that can temporaly paralyze theyre enemys and some can only cloud up the water with it, While some others can only shoot out little blobs which they use as decoys for the predator to go after while they escape.
Whales eat octopus [sperm whales have giant octopus as a favorite food]. Octopus eat each other octopus. Humans eat octopus. Anything that can catch an octopus (that isn't easy) will eat it. Killer whales [or Orcas, a kind of toothed whale] eat octopuses.
octopus have an ink gland that holds the ink until the octopus decides he is in danger and sprays its enemy with it. The ink of the octopus is toxic and if the predator stays withing reach of the ink for prolongued periods of time it can die.
