No, 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. 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.

A devilfish octopus eats crabs and other things.
Some eat smaller fish, invertibrates, Plankton, Algae... etc.
they eat crustaceans and zooplankton octopuses eat more than just that. They eat fish and crab plankton and more then I can name. They don't JUST eat crustaceans and zooplankton. People I am a expert on octopus and I still go the school.
The difference between dolphins and octopus is that dolphins have skeletons and octopuses don't! There are many differences between a dolphin and an octopus such as an octopus has tenicles and dolphins dont. Plus they eat very different diets. Octopuses may eat plankton while the dolphin eats small fish

Plankton do not eat fish. This is because plankton are normally producers meaning they produce their own food. Normally fish eat plankton.

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.
