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.
sponges, coral, jellyfish
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]
Most 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.
i don't really know your best hope is to go to another website and look there. IM SO SORRY but yea, i wanted to find this answer to but no one had answered it :)
I'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.
The animals Hydra and sponges do not have a circulatory system
octopus and sqid has blue blood
The lymphatic system
all animals have digestive systems
none all animal need at least one heart
Lower animals like the moluscsearthworm
no
circulatory system
Bacteria do not have a circulatory system
circulatory system
Example of closed Circulatory animals is worms
grasshoppers, have an open circulatory system
It helps plants and animals live. It also is apart of the circulatory system.
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 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.
Lower animals like the moluscsearthworm
yes, it has a open circulatory system, which is not contained within veins.
Diffusion.
prawns
By simple diffusion
diffusion
Some dont have any at all but most have closed cirrculatory systems.
