Blue ringed octopuses do have enough poison to kill a human.
Enough to kill 26 adults
Octopuses eat small crabs and scallops, plus some snails, fish, turtles, crustaceans (like shrimp), and other octopuses. They catch prey with their arms, then kill it by biting it with their tough beak, paralyzing the prey with a nerve poison, and softening the flesh. They then suck out the flesh. Octopuses hunt mostly at night. Only the Australian Blue-ringed octopus has a poison strong enough to kill a person. Source: enchantedlearning.com

I once saw a programme where sharks were going missing in an aquarium, it turned out to be an octopus catching and eating them, but no, the do not eat plankton.
It varies with the individual.
Octopuses are mollusks.
It may be hard to say, but it depends on the type of the jellyfish. A box jellyfish or a portuguese man of war has slightly more powerful toxic than blue ringed octopuses. Portuguese man of wars poison is very painful that it can even cause shock, fever, and lung and heart problems. Other jellyfishes like the giant jellyfish, no. The box jellyfish's venom can easily stop heart and systems functioning. But it is very weird how a lot of people say that blue ringed octopuses poison is strong enough to kill twenty to forty fully-grown humans at a time.
True. The blue-ringed octopus does have enough venom to kill a person in minutes even if the person doesn't know he/she has been poisoned.
it has poison in it and the blue ringed octopus releases it into the prey. it has poison in it and the blue ringed octopus releases it into the prey.
yes
The blue ringed octopus are quite small. They are 5 - 8 inches, or about the size of a golfball.
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.
they crawl or they swim by expelling (squirting) water
