Camels have oval-shaped red blood cells. However, their red blood cells don’t have nuclei; this is another myth that circulates. This is actually an interesting evolutionary change in the camel’s blood. Camels, as most people know, can go for a long time without water. Due to this, their blood can soak up and expand by two hundred and forty percent when they drink water and hydrate.
Most other animals can only expand their red blood cells by a hundred and fifty percent while hydrating.The oval shape of a camel’s blood cell also allows them to go long periods of time without rehydrating for another reason. This specific shape allows the blood to dehydrate without thickening too much. This allows the camel to dehydrate without worrying about their blood thickening.
