Amazing Adaptations
Learn about the unique ways that aquatic animals have adapted to survive in their habitats—from the color-changing giant Pacific octopus to the shocking electric eel to the punching peacock mantis shrimp.
Color-Changing and Shape-Shifting Octopuses
One of the most well-known residents of Surviving Through Adaptation is the giant Pacific octopus. Like other species of octopus, the giant Pacific octopus is a master of disguise and escape. It can instantaneously shift the color and texture of its skin to become virtually invisible to predators—or to wait undetected for passing prey. Its soft, boneless body allows it to shape-shift, squeezing through any space large enough to fit its small, sharp beak, which is made of a substance called chitin. Weighing an average of 50 pounds, the giant Pacific octopus is the largest species of octopus, and it can squeeze through an opening only a few inches wide.
