Other interesting facts about octopus

Octopuses are highly intelligent creatures, known for their problem-solving abilities and complex behaviors, including using tools and escaping from enclosures. They have three hearts and blue blood, which helps them survive in deep-sea environments. Additionally, octopuses can change color and texture for camouflage and communication, thanks to specialized skin cells called chromatophores. Remarkably, they have the ability to regenerate lost arms, making them resilient in their often dangerous underwater habitats.
