89. Why Do Octopuses Have Blue Blood?

What makes an octopus's blood blue instead of red? In this ocean-themed nature study for kids, discover how hemocyanin helps octopuses survive in cold, low-oxygen waters and why these creatures are some of the coolest animals in the sea.

In the companion video class about Octopuses included in the No Sweat Nature Study membership, students will learn all about octopus anatomy, how camouflage works, and the amazing ways these animals use their arms, suckers, and brains to survive. They'll even create an underwater nature journal scene featuring a camouflaged octopus blending into its habitat.
