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.

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.
The blue whale is a baleen whale.

The blue whale. Technically the whale shark isn't acually a whale, but in fact the worlds largest fish (shark). The blue whale, also happens to be the largest animal (mammal) on the planet.The blue whale is nearly twice the size of the whale shark, to 90 feet or more.
