What is the color of the frog’s red blood cells?

Frog erythrocytes are red, just like in humans. It is the erythrocytes that give the blood its red color. Red blood cells have a characteristic color due to the hemoglobin in their composition. This substance carries oxygen to the cells. But there is a frog whose blood is green. All because of the special pigment. But in most frog species, the blood is red. Frog erythrocytes are different from humans. They are larger in frogs and have a core. Therefore, in them, these cells can carry less oxygen per unit volume of blood.
