Question

which animal have blue blood ​

Answer 1

Answer:

squid , octopus, crab , certain insects

Answer 2

• Squid, Octopus, king crab, and bound insects and their larval stages have blue-colored blood.
• The reason for the blue color is that they need the supermolecule 'Haemocyanin' whereas the vertebrates have 'Haemoglobin'. each of these proteins assists in atomic number 8 transport within the body.
• The Antarctic octopus (Cirro Octopus Antarctica) is thought to own blueblood. this is often a result of its blood incorporating a copper-rich supermolecule.
• Lobsters, crabs, pillbugs, shrimp, octopus, crayfish, scallops, barnacles, snails, tiny worms (except earthworms), clams, squid, slugs, mussels, horseshoe crabs, most spiders.
