what is the animal that has blue blood?

Answer 1

All those animals that have haemocyanin as the respiratory pigment have their blood blue when oxygenated. Haemocyanin is the respiratory pigment akin to haemoglobin but hemocyanin has copper as the cofactor instead of iron which you find in haemoglobin.
Animals belonging to class crustacea and those belonging to phylum Mollusca have hemocyanin, and hence they have blue blood.
Some notable crustaceans are crabs, lobsters, shrimps.
Some notable mollusks include Snails, whelks. mytilus, oysters, chitons, squids, sepia, octopus.
Limulus, called a horseshoe crab, also has hemocyanin.

Answer 5

Squids & some species of crayfish & transleuscent cnidarians (like jellyfish & sea anemones) found in deep sea. No need of bogus long answers like someone did and made you explain all the history f the animal because blue blood in this question as the blue blood carries toxins with a protective layer of cytoplasm (cytoplasm is necessary because if it's not there, the animal will die of that toxin). The WBC in the tissues cover 70% to regulate it's body. Blue blood cells are 29% & it helps in defence. RBC functions their whole body like ours but is found in traces.

Answer 6

Horseshoe Crab - Limulus polyphemus
The pigment that carries oxygen around a horseshoe crabs body, hemolymph, contains copper. On contact with air, this gives the blood a blue appearance. In humans, and most vertebrates, the oxygen carrying pigment is haemoglobin, which contains iron giving the blood its deep red colour.
A by-product of the horseshoe crabs' blood is also an important compound in medicine used to test for a fatal bacteria in all injectible dugs and medical devices, like artificial hips.
1. This is a crab that isn't a crab! It is distantly related to spiders and scorpions. To avoid confusion, let's call it by its correct name, Limulus polyphemus. (Pronounced Lim-u-lus poly-feem-us)

2. The Limulus is a "living fossil" whose origin dates back to Triassic times, over 200 million years ago, a time when the first dinosaurs and primitive mammals appeared. Few other well-known animals can claim that record. It is not easy to be a living fossil. To apply for this category, that animal can only have, at most, a few close relatives. The body form should not have changed over the years. A true living fossil's family tree must be tens, or preferably hundreds, of millions of years old.

3. Its tail is NOT a weapon. The animal almost never carries it in an upright position so there is little chance that people might step on the upright tail. This tail, or telson, serves one real purpose: to assist the animal in turning over should a wave tip it on its back.

4. Limulus is found along the Atlantic coast, spending summers in the shallow coastal waters and winters offshore in the mud. They usually walk along the bottom, feeding on sea worms and young clams. Because of this diet, professional clam diggers have claimed that the Limulus can destroy hundreds of clams as they feed. However, it has fed this way for thousands of years and we still have clams.

5. Limulus can reach maturity in nine to 11 years. At maturity, the female is larger than the male. This is one way you can tell them apart.

6. Because Limulus has a hard outer shell (called an exoskeleton), it has to shed (molt) its shell periodically in order to grow. Many of the "dead" Limuli you find on the beach are not dead, but the castoff shells of molted Limuli. Once a Limulus sheds its old shell, it has a new, soft one that hardens in about 12 hours.

7. Limulus has four eyes - two small, simple eyes up forward and two larger, compound eyes (much like a fly's eyes) on either side of the shell.

8. To breathe, the Limulus has "gill books." Turn one over and take a look at these structures which do much the same things as your lungs. Five in number, each gill book contains 100 "leaves" resembling parchment paper. The total surface area is large enough to permit the exchange of oxygen and carbon dioxide. In addition to permitting exchange of these gases, the gill books can sometimes be used by the animal as paddles while swimming upside down in the water.

9. Limulus is a true "blue blood" for, while human blood is red, the blood of this creature is a light blue. Human blood is red because it has a red pigment called hemoglobin which contains iron. The Limulus blood contains copper rather than hemoglobin thus giving the blood its blue color. The animal's blood also contains fantastically sensitive chemicals used by researchers in discovering harmful bacteria called endotoxins, sometimes found in human blood. In short, the blood of this ancient animal might well save your life some day. (See update below.)

10. Limulus has one pair of feeding legs, four pairs of walking-feeding legs, and one longer pair of walking legs that shove the body forward.

Answer 7

According to the source listed below...
Squids are blue-blooded animals because their respiratory-system pigment is a copper compound rather than the red iron found in mammals

Answer 8

Many other lower animals carry oxygen in their blood stream by means of a dissolved substance called hemocyanin which is blue. At least it is blue when it is oxygenated, but colorless after the oxygen is released. Hemocyanin is much like hemoglobin except that the iron atom in the protein molecule is replaced by one of copper. The lobster, crab, crayfish, scorpion, octopus, squid, clam and mussel all have this blue blood. A few marine worms have green blood.

Answer 9

insects have blue blood . yes it is true and proved. try hitting a wasp or a beetle, a shade of blue coloured blood willrun out if theinsect has no other persons blood
