How many blood cells do ants have

Why don't insects have red blood?

In fact, almost all insect species do without red blood. You don't even need that, because you get fresh oxygen from a widely branched windpipe system. This tracheal system reaches almost every cell, so oxygen-carrying red blood cells are not necessary.

Strictly speaking, insects have no blood at all, because their circulatory system, unlike that of vertebrates, is open; the colorless blood fluid, also called hemolymph, circulates freely throughout the body and thus transports nutrients through the body.

The mosquito larvae Chironomus however, they cannot do without oxygen-transporting molecules. They live in oxygen-poor waters and have the same blood pigment as vertebrates: hemoglobin. The mosquito larvae have no blood cells, however, the hemoglobin floats freely in the hemolymph.

The red hemoglobin - the color is the result of the central iron atom - is most widespread in the animal kingdom. In addition to vertebrates, it is also found in many snails, mussels and earthworms. However, there are three other blood pigments: Haemerythrin, the blood pigment of some annelids, is also iron-containing and therefore red. Many crabs and snails, such as the Roman snail, transport oxygen via the copper-containing, blue hemocyanin. The green colored chlorocruorin of a few families of annelid worms is similar in its molecular structure to hemoglobin.
