Animals Octopus Intelligence and Problem-Solving
Octopuses have nine brains - one central brain and eight mini-brains in their arms. Each arm can solve problems independently and even taste what it touches. Octopuses can open childproof bottles, navigate mazes, use tools, and recognize individual humans. Their intelligence evolved completely independently from vertebrates, representing a second origin of complex cognition on Earth.

An octopus has three hearts and blue blood due to copper-based hemocyanin instead of iron-based hemoglobin!
