Octopuses are downright fascinating creatures. According to a study, they are the most intelligent invertebrates.
Many researchers kept octopuses under observation in order to study their behavior. Thus, it turned out that they are able to handle extreme situations and adapt quickly to their environment. For example, octopuses can disguise and hide under different objects in order to escape their predators.
The video below proves just how smart these creatures really are. After being trapped inside a closed jar, this octopus manages to escape, although the lid was firmly closed.
