With their blue blood, big brains and eight arms, octopuses are dramatically different from any other being.

Octopuses are masters of camouflage and known for their incredible escapes from tight spots. New research shows that they are highly intelligent creatures, and while they prefer to be alone, they will interact with humans and display unique personality traits.

In Octopus Ocean, discover the mysteries and histories of octopuses big and small—their biology, habitat and habits—and explore the top threats to their future, including warming oceans, over-fishing and pollution.
