The Distinct Color of Octopus Blood Unlike humans and most other animals, octopuses have blue blood. This coloration stems from the protein responsible for oxygen transport within their circulatory system. Instead of the iron-based hemoglobin found in red blood, octopuses use a copper.
The ability is literally in their blood. The same pigment that gives the octopus blood its blue color, hemocyanin, is responsible for keeping the species alive at extreme temperatures. Hemocyanin is a blood-borne protein containing copper atoms that bind to an equal number of oxygen atoms.
It's part of the blood plasma in invertebrates. The octopus is a fascinating and enigmatic creature, known for its intelligence, camouflage abilities, and unique physiology. One of the most intriguing aspects of an octopus's biology is the colour of its blood.
But what colour is it, exactly? The answer may surprise you! The blood of octopuses and squids is blue because they use a different protein for oxygen transport than human beings do. This protein, hemocyanin, relies on copper to bind with oxygen, which causes the blood's discoloration. Squids and octopuses have adapted to their environment by changing the hemocyanin concentration in their blood.
Octopus blood is unique due to its striking blue color. This distinctive hue arises from the presence of hemocyanin, a copper. The blood of an octopus is blue.
This unique color comes from a copper-rich protein called hemocyanin, which is used for transporting oxygen in their bodies. The blood itself is blue-green in color because it possesses hemocyanin, a copper-containing protein typical in cephalopods-cuttlefish, octopuses, and squids. Why do octopuses have blue blood, how it helps them thrive in extreme ocean depths, and what makes them the ultimate underwater royalty.

The blue color of octopus blood comes from a copper-rich protein called hemocyanin, which serves a similar purpose to the hemoglobin found in human blood. While hemoglobin uses iron to bind oxygen and appears red when oxygenated, hemocyanin uses copper, which gives it a blue hue when oxygen binds to it.
