Also some animals get sick to scare away predators. Some scientists think that this is why some people literally get sick when they get too scared, as we had originally evolved to scare predators away from us! I’d certainly leave the cinema if someone did that behind me!
Karen, I don’t think eating their own vomit is coprophagia. Just poo.
Camels eat hay and grasses that contain a lot of cellulose. This is very hard to digest so they rarely get much nutrients from the first round of digestion. Vomiting and pooing their food releases some of the nutrients, so by eating this regurgitated or pooed material, they gain additional nutrients that they couldn’t obtain the first time around. Great question again Rubaty 🙂
