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.
Animals without circulatory systems include sponges, cnidarians like jellyfish, and some flatworms. These animals rely on diffusion to transport nutrients and gases throughout their bodies. They typically have simple body plans and do not require the complex transport system of a circulatory system.
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.
The vascular system in plants is analogous to the circulatory system in animals. Both systems are responsible for the transportation of fluids and nutrients throughout the organism. In plants, the vascular system consists of xylem and phloem, while in animals, the circulatory system includes the heart, blood vessels, and blood.
No, mollusks typically have an open circulatory system, where the blood flows around the body cavity and directly bathes the organs. This is in contrast to closed circulatory systems found in some other animals where the blood flows through vessels.
Invertebrates like insects and mollusks have a single circulatory system. This system does not differentiate between oxygenated and deoxygenated blood, instead using a fluid called hemolymph to transport nutrients and waste throughout the body.
Spiders have an open circulatory system. This means that their blood, called hemolymph, flows freely within their body cavity instead of being contained within blood vessels like in animals with closed circulatory systems. Hemolymph plays a role in nutrient transport, waste removal, and exerting pressure to help with movement in spiders.
A single loop circulatory system is a type of circulatory system found in some simpler animals, where blood flows through the body in one continuous loop. This type of system lacks separate systemic and pulmonary circuits, with blood traveling from the heart to the gills or lungs, then to the rest of the body, and back to the heart. Examples of organisms with a single loop circulatory system include fish.
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.
yes, it has a open circulatory system, which is not contained within veins.
prawns
Diffusion.
By simple diffusion

Some dont have any at all but most have closed cirrculatory systems.
Arthropods and most mollusks have an open circulatory system.
No, dandelions do not have a circulatory system like animals do. They have a system of vessels that transport water and nutrients within the plant, but it is not the same as a circulatory system found in animals.
