Did you know that octopuses have the largest brains of all the known invertebrates in the world? They also have brains in their arms too! Each arm has a bunch of neurons that work together to help an octopus move in a coordinated way. All these brains make octopuses incredibly intelligent.

Here another cool fact. Octopuses have chromatophores in their skin. Chromatophores are specialized cells containing pigments that allow them to change color and create intricate patterns. These cells help them hide by matching the colors and patterns of their surroundings, like rocks or seaweed. Octopuses use this remarkable skill not just for camouflage but also to communicate with other octopuses and express their emotions.

We hope you and your student(s) enjoyed learning about these intelligent invertebrates! If you want to learn even more, head over to our website and download one of our many lesson plans about animals, full of activities, worksheets, and more!
