In Animal Kingdom, Blood Comes in a Rainbow of Colors. The Antarctic octopus, pictured, has a copper-rich protein in its blood that turns the vital fluid blue. Please be respectful of copyright.
Octopuses, lobsters, and horseshoe crabs use hemocyanin, which has copper instead of iron, and is blue instead of red—that's why these creatures bleed blue. Other related molecules are responsible for the violet blood of some marine worms, and the green blood of leeches.
One group of segmented marine worms has pink blood. This is because the molecule that carries the oxygen is a type of blood pigment, known as hemerythrin, which is described as pink or purple. A few species of segmented worms don't have any oxygen-carrying molecules at all, so their blood is colourless.
Sea squirts have purple blood. And a few rare animals have blood that is completely color- less. So what is the reason for all of these different colors of blood in animals? The blood of a horseshoe crab is blue because of a mol- ecule called a respiratory pig- ment.
Octopuses and horseshoe crabs have blue blood because the protein transporting oxygen in their blood, hemocyanin, contains copper, instead of iron, making their blood appear blue rather than red.
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
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.
Indeed, most mammal, fish, reptile, amphibian, and bird blood is red because of hemoglobin, whose protein is made of hemes, or iron-containing molecules that fuse with oxygen.
The icefish of the Channichthyidae family are unusual in several ways — they lack scales and have transparent bones, for example — but what stands out most is their so-called white blood, which is unique among vertebrates.
Spiders usually have eight eyes (some have six or fewer), but few have good eyesight. They rely instead on touch, vibration and taste stimuli to navigate and find their prey.
Prasinohaema prehensicauda, found in New Guinea, is a green-blooded lizard with high concentrations of biliverdin, a toxic green bile pigment. Green blood is one of the most unusual characteristics in the animal kingdom—and the hallmark of a group of lizards in New Guinea.
The circulatory system in cockroaches is open type. The colour of the blood of the cockroach is not red it is colourless due to the absence of hemoglobin. The blood of the cockroach is known as hemolymph.
Hippopotamus gives the milk of blue color. Blue milk, also known as Bantha milk, was a rich blue-colored milk produced by female banthas.
Blue is one of the rarest of colors in nature. Even the few animals and plants that appear blue don't actually contain the color. These vibrant blue organisms have developed some unique features that use the physics of light.
Did anyone know that some animals have blue blood, especially when it is exposed to oxygen? 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.
Brachiopods have black blood. Octopuses have a copper-based blood called hemocyanin that can absorb all colors except blue, which it reflects, hence making the octopus' blood appear blue.
Sea cucumbers have yellow blood due to a high concentration of a yellow vanadium-based pigment called vanabin. Some members of the phylum Annelida (segmented worms and leeches) have a greenish respiratory pigment called chlorocruorin.
She has taught science courses at the high school, college, and graduate levels. The hippopotamus or hippo mystified ancient Greeks because it appeared to sweat blood. Although hippos do sweat a red liquid, it isn't blood. The animals secrete a sticky liquid that acts as a sunscreen and topical antibiotic.
Amblyodipsas is a genus of snakes found in Africa. Currently, 9 species are recognized. These snakes are often known as purple-glossed snakes or glossy snakes. Although rear-fanged, all species are considered harmless, but their venom has not been well studied.
Flatworms, nematodes, and even cnidarians (jellyfish, and corals) generally do not have a circulatory system and thus do not have their own blood. Their body cavity also has no lining or any fluid within it. They obtain the nutrients & oxygen directly from the water in which they live.
They discovered that most snakes have three visual pigments, two of which are in cones. Snakes are therefore likely to be dichromatic in daylight, meaning they see two primary colours compared to the three that humans see.
Some spiders, horseshoe crabs, and scorpions also have blue blood.
Octopuses have blue blood, three hearts and a doughnut-shaped brain. But these aren't even the most unusual things about them!
