Snails, Spiders, and Octopi all have Blue Blood. Did You Know? 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.
Some animals like spiders and other arthropods such as horseshoe crabs, octopi, snails and lobsters, have blue blood due to the presence of copper-based hemocyanin.
Spiders (as well as horseshoe crabs and certain other arthropods) have blue blood due to the presence of copper-based hemocyanin in their blood. Some animals, such as the sea cucumbers, even have yellow blood.
The spiders have circulating blood in their bodies. The colourless blood, called hemolymph, transports nutrients, hormones, oxygen and cells. The blood also serves another purpose. It is used locally to raise the blood pressure during moulting (shedding of old skin) and stretching the legs.
Yellow blood is fairly unusual and is only seen in tunicates, sea cucumbers, and a few types of beetles. The color is caused by high concentrations of vanabin proteins in their blood. Vanabin contains the element vanadium. Unlike other respiratory pigments, vanabin doesn't transport oxygen.
Peanut worms, duck leeches, and bristle worms, all of which live in the ocean, use the protein hemerythrin to carry oxygen in the blood. Without oxygen, their blood is clear in color. When it carries oxygen, it turns purple.

BATON ROUGE – Green blood is one of the most unusual characteristics in the animal kingdom, but it's the hallmark of a group of lizards in New Guinea. Prasinohaema are green-blooded skinks, or a type of lizard.
There is evidence consistent with the idea of pain in crustaceans, insects and, to a lesser extent, spiders. There is little evidence of pain in millipedes, centipedes, scorpions, and horseshoe crabs but there have been few investigations of these groups.
Spider blood (known as haemolymph) is blue-green in colour.
The short answer is ants have something similar to blood, but scientists call it “haemolymph”. It is yellowish or greenish. In vertebrates (animals with backbones such as humans, cats, dogs, snakes, birds and frogs) blood's main job is to move important things around the body.
In all spiders the abdomen contains a tube-shaped heart, which usually has a variable number of openings (ostia) along its sides and one artery to carry blood (hemolymph) forward and one to carry it backward when the heart contracts.
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.
Water is necessary for survival, but they can survive several months without it. For house spiders (and some other species), drinking once every few days or so may be enough to keep them alive. However, if the spider is under stress (from a lack of food, for example), it may need to drink more often.
Unlike your blood, arachnid blood appears blue-ish or clear, as they do not have hemoglobin (which is responsible for your blood's color).
Answer and Explanation: Spiders don't run out of silk because they are constantly making it as they are using it. This happens in specialized body structures called spinnerets. Spinnerets are glands at the base of a spider's abdomen that produce silk.
Spiders can't move the air to make noises like people do with their vocal cords and don't have ears to hear. Instead, they communicate by sending sound vibrations through the ground.
“While spiders might not form the same types of bonds with their humans as cats or dogs, I'd like to think that they might be able to recognize people and that people can earn their trust and perhaps even their love, whatever love might mean in a spider's world,” Wolfe told CNN.
Some spiders have life spans of less than a year, while others may live for up to twenty years. However, spiders face many dangers that reduce their chances of reaching a ripe old age. Spiders and their eggs and young are food for many animals.
Hippopotamus: It is also known as hippo or river hippopotamus, which is a large semiaquatic mammal generally found in Sub-Saharan Africa. The milk produced by hippo females is pink in color.
Snails: Even though their mouths are no larger than the head of a pin, they can have over 25,000 teeth over a lifetime – which are located on the tongue and continually lost and replaced like a shark! Snails have more teeth than any animal.
Icefishes of the family Channichthyidae has white blood.
Spiders do not sleep in the same way that humans do, but like us, they do have daily cycles of activity and rest. Spiders can't close their eyes because they don't have eyelids but they reduce their activity levels and lower their metabolic rate to conserve energy.
What color is a lobster's blood? Lobster blood is colorless. When exposed to oxygen, it develops a bluish color.
Light blue is thought to repel spiders for several reasons. One of the reasons may be that since blue is the color of the sky, it can make spiders feel like they're in an open space and more vulnerable. Spiders are most exploratory at night and prefer to stay in the dark as much as possible.
