That's cool and all but this is getting off topic.

I found as much evidence as I possibly could to confirm that arthropods do have blood, its not the same kind as vertebrates but it still counts as blood.

Here as my sources: Hemolymph Open Circulatory System

Here are also some key quotes from those said sources: "Hemolymph, or haemolymph, is a fluid, analogous to the blood in vertebrates, that circulates in the interior of the arthropod body remaining in direct contact with the animal's tissues." "In arthropods, the open circulatory system is a system in which a fluid in a cavity called the hemocoel bathes the organs directly with oxygen and nutrients and there is no distinction between blood and interstitial fluid; this combined fluid is called hemolymph or haemolymph."

There may be some arthropods that don't have hemolymph but they are exceptions as every living thing on this planet can have an exception but we're talking about the majority here.

Hemolymph's lack of capability to carry oxygen does NOT mean it isn't like blood, insects have their own ways of transporting oxygen throughout their body which makes it unnecessary for their hemolymph to do the job whereas humans don't have that kind of special system so our blood transports oxygen. In its essence, blood is circulatory fluid and vertebrae do have circulatory fluid which acts like blood.

I really need your sources and a better counter-argument than you going off topic or making claims without citing sources while I'm over here citing mine.
