Both are sea-dwelling, eukaryotic animals with a complex nervous system and a very intelligent brain, but that's where the similarities end. Octopi are molluscs, which makes them quite different from vertebrates such as whales. The two different phylums that these animals belong to, mollusca and chordata, have diverged very early in evolutionary history.
The first multicellular organisms evolved into different branches of animals. Some had an internal skeleton, such as the fish that would eventually evolve into amphibians, reptiles, and mammals (like whales). Others had an external skeleton, like crustaceans and insects, and others again had no skeleton at all, like octopi. That makes whales and octopi fundamentally different.
the killer whale
Humpback whale, sperm whale, pilot whale, Beluga, minke, blue whale and fin whale have similar adaptations.
No an octopus is not bigger than a whale
No, a blue-ringed octopus cannot kill a whale. Blue-ringed octopuses are small, venomous creatures that primarily prey on small fish and crustaceans. Their venom is potent enough to kill a human, but it is not powerful enough to take down a large marine mammal like a whale. Whales are much larger and have thick blubber that would provide protection against the octopus's venom.

Blue -Ringed Octopus: Has blue rings on the outside;
A blue ringed octopus.
Phytoplankton gets eaten by zooplankton, which gets eaten by a small fish, which gets eaten by a shark, which dies than is eaten by a crab, which is eaten by a blue ringed octopus. The blue-ringed octopus eats crab, hermit crab, shrimp, and various small fish.
The blue ringed octopus has yellowish skin with blue and black rings all over its body
