Emily Landis’s Reviews > The Octopus Scientists: Exploring the Mind of a Mollusk > Status Update

DID YOU KNOW?… octopuses have 3 hearts & blue blood with copper binding to oxygen instead of iron. Some glow in the dark, some are completely see-through, and some (the giant pacific octopus) can stretch longer than a limousine!! These cephalopods are over 300 million years old and hold an extreme amount of intelligence in just one tentacle sucker. Wowowowow!!! Aliens?? Maybeeee 🤣🐙
