What do giant pacific octopus eat?
The giant octopus usually feeds on bivalves, crabs, and lobster, but will eat a range of species. They have also been observed eating fish, sharks, and even birds.
Yes, very. Extreme caution should be used around these creatures, as their bite carries tetrodotoxin, a neurotoxin that can cause paralysis of the diaphragm (suffocation) or of the heart (heart failure).
Why did Lyle Zapato make the fake tree octopus site?
To let people know that not everything on the web is true, plus he has ALOT of free time.
What invertebrate group does the octopus belong to?
mollusk, polycepoda
Intelligent Invertebrate: The octopus - a cephalopod - is one of the largest, fastest and most intelligent of all invertebrates.
This information was taken from "Animalplanet.com".
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?
yes the blue ringed octopus is harmful to human. its beak is powerful enough to penetrate diver's suit even!
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.
Do blue-ringed octopuses bite or sting?
Tetrodoxtin is the type of toxin contained in blue-ringed octopus saliva, the same type of poison that puffer fish have. A milligram or less, about a pin-head amount, is all that is needed to kill an adult human.

Octopus belong to which family?
Octopus means a member of the order Octopoda. Since orders are higher than families in the classification scheme, you'd have to be more specific about which particular type of octopus in order for us to choose one of the several families in that order.

adult octopi eat crabs, clams, snails, small fish and even other smaller octopi. they use small parrot like beaks to crush their pray.
