Detailed explanation-1: -Snails, spiders and octopi have something in common-they all have blue blood! We’re not talking in the sense of royalty, these creatures literally have blue blood. So why is their blood blue and ours red? One of the purposes of blood is to carry oxygen around the body.
Detailed explanation-2: -Can you guess what animals might have blue blood? Lobsters, crabs, pillbugs, shrimp, octopus, crayfish, scallops, barnacles, snails, small worms (except earthworms), clams, squid, slugs, mussels, horseshoe crabs, most spiders.
Detailed explanation-3: -Why do crabs have blue blood and humans have red blood ?
Detailed explanation-4: -The mollusk’s blue colour comes from the copper atoms in the blood pigment haemocyanin that transport oxygen around the tissue of the palm-sized marine mollusk.
Detailed explanation-5: -Hemocyanin is a respiratory pigment found only in some invertebrates-molluscs (e.g. snails, octopuses, squids) and arthropods (e.g. scorpions, spiders, horseshoe crabs, lobsters). It is an extracellular protein, i.e. it is not carried in blood cells, but it floats freely dissolved in the hemolymph.
