What animals eat poop: The weird world of poop-eaters

When we think of poop, we usually associate it with something smelly and gross. However, for some animals, poop serves as a source of nutrition. While it may seem strange to us, poop-eating or coprophagy is a common practice in the animal kingdom. In this article, we will explore the fascinating world of poop-eaters and the reasons behind their behavior.

Why Do Animals Eat Poop?

Before we dive into the specifics, let’s first understand why animals engage in coprophagy. The practice of eating poop is a natural and adaptive behavior seen in many animals. Here are some of the possible reasons behind coprophagy:

  • Nutrient deficiency: Animals may eat poop if their diet lacks certain essential nutrients. Eating poop allows them to obtain the missing nutrients.
  • Digestion improvement: Some animals, like rabbits and other rodents, eat their own poop to re-digest their food for better nutrient absorption.
  • Cleaning: Many animals eat poop as a way to clean their environment. This is common in social animals like dogs and primates where eating poop helps to keep their living spaces clean.
  • Mother’s milk substitute: Some animals, like elephants and koalas, eat their mother’s poop for the gut microbes that help them digest tough plant matter. This helps them adapt to a plant-based diet from an early age.

Animals that Eat Their Own Poop

There are different types of coprophagy, the most common one being where animals eat their own poop. Here are some animals that engage in self-coprophagy and the reasons behind their behavior:

Rabbits

Rabbits, hares, and rodents like guinea pigs and hamsters eat their own poop, called cecotropes, to re-digest their food for better nutrition. Cecotropes are the soft, green or brown, and shiny pellets that rabbits produce after a meal. These pellets contain beneficial bacteria and micronutrients, such as vitamin K and B vitamins, that the rabbits’ digestive system couldn’t absorb the first time around.

Dogs

Many dog owners are familiar with the unpleasant habit of their pets eating poop. Dogs engage in coprophagy for various reasons. It could be because of the nutrition they get from it, due to poor diet or poor absorption of nutrients. They could be cleaning their surroundings or simply indulging in the behavior because they find it delicious. Despite the stereotype, not all dogs eat poop, and it is more common in puppies than adult dogs. If your dog is eating poop excessively, take it to a veterinarian to rule out any health issues.

Turtles

Some species of turtles, such as the red-eared slider and the painted turtle, are known to eat their own feces. Turtles’ digestive systems are not very efficient, so when they eat, a lot of nutrients pass undigested. Eating poop helps them obtain these nutrients as well as beneficial gut microbes. Turtles in the wild do not eat poop often, only in captivity do they resort to such behavior due to limited diet and space.

Animals that Eat Another Animal’s Poop

Animals do not just eat their own poop, but also that of other animals. This is called coprophagia or heterocoprophagy. Here are some animals that engage in coprophagia and the reasons behind their behavior:

Elephants

Elephants are known to eat the poop of other animals, called dung, to supplement their diet. Dung is rich in fiber and nutrients that help elephants digest their plant-based diet. It also contains beneficial microbes that help elephants’ digestive system function efficiently. In addition to this, elephants use dung as a social cue to communicate with each other.

Kangaroos

Kangaroos are herbivores that eat tough plant material. They practice coprophagy to help them digest these plants better. Kangaroos produce a special type of dung called “pap,” which contains beneficial bacteria and other enzymes that help break down cellulose. The kangaroos then eat the pap to extract the maximum nutrition from their food.

Birds

Some bird species practice coprophagy as a way to obtain essential nutrients, such as calcium, from eggshells. The eggshells provide a good source of calcium that helps in the formation of their own eggshells. Coprophagy is also seen in some seabirds and pigeons, where they consume their own droppings as a way of recycling nutrients and to maintain efficient water balance in their bodies.

The Risks of Eating Poop

While coprophagy is a necessary and natural behavior in some animals, it can have harmful effects, especially in humans. Eating or coming into contact with poop can transmit diseases and parasites. Therefore, it is crucial to practice good hygiene and seek veterinary advice if your pet is engaging in excessive coprophagy.

Conclusion

While the thought of eating poop might make us cringe, it is a necessary and beneficial part of the animal kingdom. From rabbits to elephants, coprophagy serves as a mechanism to meet nutritional and environmental demands. Understanding this behavior can help us appreciate the complexity and diversity of the animal kingdom.
