Most animals don't have red blood. Those that do have red blood are most of the vertebrates. Some fish, especially cold-water fish, lack hemoglobin. Octopi have copper-based green blood. Insects and other arthropods' blood is called hemolymph, which is not pigmented as a rule. Earthworms have red blood that, interestingly enough, does contain hemoglobin. Most other annelids do not have red blood. Echinoderms (starfish, sea lilies, and sea cucumbers) do not have blood. Neither do sponges, coelenterates, and flatworms.

flatworms: Unlike other bilaterians, they have no body cavity, and no specialized circulatory and respiratory organs, which restricts them to have flattened shapes that allow oxygen and nutrients to pass through their bodies by diffusion. [wikipedia]

∙ 15y agoMost animals use haemoglobin as the oxygen carrying component in their blood. Whether as carboxyhaemoglobin, oxyhaemoglobin or caronmonoxyhaemoglobin this renders the blood red.
The only animals not using this iron based compound are the octopus and other molluscs and some arthropods such as the horseshoe crab. They use hemocyanin, a copper based protein. Hemocyanins are colorless when deoxygenated and blue when oxygenated. Unlike haemoglobin the hemocyanin is not associated with blood cells but floats free in the blood.

∙ 15y agoI'm pretty sure ALL animals have a circulatory system, because it includes your heart, blood, arteries, veins, and more; therefore if you didn't have one you would die.

circulatory system
What kind of circulatory system do bacteria have?
Bacteria do not have a circulatory system
System that transports materials throughout the body?
circulatory system
Animals with a closed circulatory system?
Example of closed Circulatory animals is worms
What are examples of animals with an open circulatory system?
grasshoppers, have an open circulatory system
How is carbon dioxide part of the circulatory system?
It helps plants and animals live. It also is apart of the circulatory system.
What type of circulatory system do animals that use lungs for breathing have?
A circulatory system that involves the lungs is referred to as a double circulatory system. This is opposed to a single loop circulation that fishes have.
Animals that use lungs for breathing have this type of circulatory system?
Animals that breathe using lungs have a pulmonary circulatory system. In this system, the lungs are dependent on the flow of blood from the systemic circulatory system, which works in tandem with the pulmonary system to provide blood flow to these vital organs.
What animals have a single circulatory system?
Lower animals like the moluscsearthworm
Does a garter snake have a circulatory system?
yes, it has a open circulatory system, which is not contained within veins.
How are materials transported for animals that don't have a circulatory system?
Diffusion.
Which animals have open circulatory system toads or prawns?
prawns
How do animals with no circulatory system get their material needed?
By simple diffusion
In animals that lack a circulatory system how are materials transported?
diffusion
Is the circulatory system open or closed?
