How intelligent are octopus compared to other animals?

Yet octopuses are extremely intelligent, with a larger brain for their body size than all animals except birds and mammals. They are capable of high-order cognitive behaviors, including tool use and problem-solving, even figuring out how to unscrew jar lids to access food.

Are octopus intelligent creatures?

Octopuses have demonstrated intelligence in a number of ways, says Jon. ‘In experiments they’ve solved mazes and completed tricky tasks to get food rewards.
