Octopuses are some of the coolest and most intelligent creatures in the ocean. They can solve puzzles, mimic other animals, and even use tools, which is why they’re often considered some of the smartest animals on Earth. But there’s so much more to them than just their brains. With their incredible ability to camouflage, their unique anatomy, and their complex behaviors, octopuses are truly nature’s little marvels. In this post, we’re going to count down the 10 smartest octopuses, starting with the least intelligent and working our way up to the most brainy of them all. So, stick around to learn more about these fascinating creatures and, in turn, discover the hidden brilliance that truly sets them apart from other animals!
What Makes Octopuses So Intelligent?
Octopuses are incredibly unique animals with exceptional intelligence. Unlike most creatures, their nervous system is highly distributed, with neurons spread throughout their arms, allowing them to think and act independently. This makes them one of the most advanced problem-solvers in the animal kingdom. They can figure out how to open jars, escape enclosures, and even manipulate objects to suit their needs.
But it’s not just their problem-solving abilities that make them special. Octopuses have advanced communication skills, using body language, color changes, and postures to express themselves. Their ability to camouflage themselves, blending seamlessly with their surroundings, is a direct reflection of their cognitive sophistication. Beyond just survival, these abilities demonstrate the beauty of their adaptive intelligence.
As we explore these fascinating creatures, it’s important to appreciate not only their cognitive abilities but also their vital role in the ecosystem. They help maintain balance in marine environments and serve as a reminder of how complex and interconnected nature is.

While it doesn’t engage in complex tool use, it exhibits creativity in using its surroundings for protection. Its ability to adapt to new challenges makes it a fascinating creature to study.
Why is it intelligent?
This octopus naturally demonstrates an ability to assess threats and take immediate action. Moreover, its intelligence is primarily focused on self-preservation, constantly adapting its behaviors for survival in different environments.

7. Veined Octopus (Amphioctopus aculeatus)
The Veined Octopus stands out for its use of tools, such as coconut shells, to build shelters. This remarkable ability to use objects for practical purposes shows a high level of cognitive processing. It’s a perfect example of how octopuses can adapt and survive by thinking creatively.
Why is it intelligent?
Its use of tools and problem-solving strategies for shelter demonstrates an impressive level of understanding. The Veined Octopus shows that intelligence can be simple yet effective when used for survival.

6. Coconut Octopus (Amphioctopus marginatus)
The Coconut Octopus is one of the most creative tool users among octopuses. It uses coconut shells not only for shelter but also as a mobile escape tactic. This ability to manipulate objects showcases its advanced intelligence in both problem-solving and planning ahead.
Why is it intelligent?
Its ability to collect and use tools for shelter and survival is a testament to its cognitive flexibility. The Coconut Octopus shows that intelligence is not just about solving puzzles but also about understanding how to manipulate the environment to one’s advantage.

5. Giant Pacific Octopus (Enteroctopus dofleini)
The Giant Pacific Octopus is a true problem-solver. Known for its ability to open jars, navigate mazes, and escape enclosures, this species has been extensively studied for its intelligence. It demonstrates both short- and long-term memory and an ability to adapt its behaviors to new challenges.
Why is it intelligent?
The Giant Pacific Octopus’s remarkable problem-solving skills, as well as its ability to learn through experience and retain memories, set it apart.
