Octopus ink because they need to get away from animals so the ink blinds them so the octopus can swim away.
No- they'd break their beaks if they tried! Giant octopus are strong, but not so strong as to be able to do THAT. Instead, octopus make their homes in undersea burrows beneath rocky clefts, small underwater caves, and anywhere else that can provide shelter, including the wrecks of sunken ships. Contrary to popular belief, they are not dangerous to humans and tend to be very shy of them.

Well in someplaces I would say yes. The reason for this is because when I went to Hawaii people use octopus as a big source of food.
To kill it you bite/stab/smash its brain between the eyes, immediately killing it. The octopus skin then turns white when its dead.

To cook, you can batter it like calamari...boil, then roll in flour, and cook in hot oil. Or, you can boil it and eat with salt, limu seaweed and green onions.
No -- the ink cannot. And in fact, squid ink (very close cousin of octopusses) -- is eaten as a sauce on pasta -- quite a delicacy! The Blue-ringed Octopus of Austrialia however is deadly poisonous. Its saliva contains tetradotoxin -- a truly nasty neurotoxin that blocks the sodium channel and makes you lose control of the muscles you need to breathe (that and 5-hydroytriptamine (5HT) being signature parts of the weird and very effective toxin cocktail that appears in molluscs). Note though -- it's not the ink -- it's the saliva, so they have to bite you to deliver it (it would seem). Most octopusses, however, aren't poisonous at all, and in fact are very intelligent. If you have the right qeuipment, they can even make good pets.
How does a octopus exchange gases?
The "water-vascular" system uses ocean currents to move water throughout their body, and the starfish use their gills to take oxygen from that water as it circulates.
Is a baby blue ringed octopus poisonous?

Alright, this may be a joke, but I'm going to respond to it anyway. Yes, of course an octopus lives in water, it is a cephalopod, meaning inner shell with legs. It is a subspecies of mollusk meaning shelled animal. Mollusks store water inside their bodies and live outside of water for long periods of time, but the octopus can only do this for a few minutes before it dies. If you're asking this you either must not know that much about the ocean (hint hint), or you are just trying to play a prank on someone and take up their time in writing this response. So, how's that for an answer, huh?
How strong is a octopuses suction cups?
It depends on the size of it. They can range from 8 inches to 20 feet.
What is the difference between a squid an octopus?
- When hunting, some octopuses inject poison into the prey, causing paralysis.
- Octopuses range in size from 1 cm to more than 5 m in length, while squids range from 1 cm to 20 m.
- Octopuses live in dens on the sea floor. Squids live in the open oceans.
- Both octopuses and squids are related to snails and other molluscs. Unlike snails, octopuses no longer have any remnant of a shell. Squids possess a stiff structure known as a pen, that acts as a flexible backbone.
- Octopuses are solitary animals that live alone in dens.
Some squids live in large schools, others are solitary. Some squids school when young and become solitary later in life.
- Squid have two tentacles and eight arms, and octopuses just have eight arms.
Edit: This list seems to be all wrong (except the very last point, which I need not discuss), thusly highly misleading.
- All squids and octopuses have a venom gland and venomous bite

- Deep/open. I'll let you have this one because I can't fact-check it in 2 minutes (remember, I found this question because I'm looking for the answers myself)
- This could be right. I remember watching a highly flexible octopus (on a show about problem solving abilities in animals). Squids seem to be less prone to changing shape.
- I've seen schools of squids. This one could be right too.
What abiotic factors do octopus need to survive?
Octopus are very good uses as for having as a pet. They bring joy to kids and they are very known to be looked at in aquariums. They are also good uses for bugs and eating other animals that you don't like. But other wise if you don't need an Octopus for any of these reason then you don't need one at all.
