Coprophagy
1 answer
Coprophagy is the act of an organism consuming feces. While it may seem unusual and unhygienic, coprophagy actually occurs in several species across the animal kingdom. Some animals, such as rabbits, practice coprophagy as a means of obtaining essential nutrients, specifically vitamin B12, that their digestive systems do not fully extract during the initial digestion of their food. In these cases, animals will eat their own feces or the feces of others in order to obtain these nutrients. Coprophagy can also serve other purposes, such as aiding in digestion or recycling nutrients in certain ecological systems. Overall, while coprophagy may seem strange to humans, it is a natural behavior exhibited by various animal species for survival and nutrition purposes.
