Why Some Animals Have Blue Blood — The Truth Will BLOW Your Mind!
You’ve heard of red blood, but did you know some animals literally bleed blue like royalty? Scientists were SHOCKED to discover that these creatures use copper instead of iron to survive extreme environments. From ancient survivors to deep-sea hunters, here’s a list of the 6 animals that have blue blood.
Horseshoe Crab
It has blue blood due to hemocyanin, a copper-based molecule instead of iron. Their blood turns blue when copper binds with oxygen.
Octopus
It uses hemocyanin to survive in cold, low-oxygen ocean environments. Blue blood helps transport oxygen more efficiently than hemoglobin in cold water.
Squid
These are like octopuses. Squids also rely on copper-rich hemocyanin. Blue blood allows them to stay active in deep, chilly waters.
Snails
Many snail species have blue blood due to hemocyanin in their circulatory system. It works better than red blood in low-oxygen habitats like moist soil or water.
Spiders
Their open circulatory system uses hemocyanin dissolved directly in blood. Blue blood helps spiders function across varied temperatures.
Lobsters
Blue blood helps lobsters survive in cold, deep ocean water. Hemocyanin functions efficiently even when oxygen levels drop underwater.
