Animal Coprophagy – Recycling Poop — A Caracara on a Capybara- both sometimes eat dung

One aspect of design in the natural world is that virtually no food goes to waste. To that point, researchers have discovered many instances of animal coprophagy, poop eating. A study published in the journal Animal Behaviour documents 150 species of animals ranging from adult black bears to baby koalas recycling poop.

Many of the animals could not survive if they didn’t eat the feces of other animals. One example is pikas, small mountain-dwelling mammals on the Tibetan Plateau. They could not survive the harsh winters if they didn’t eat the droppings of Yaks. Blind cave fish can’t leave the cave to forage for food, so they survive by eating the guano of bats that inhabit the caves. Cows have multiple compartments for processing food, but rabbits do not. Rabbits and other small animals survive by eating the droppings of larger animals that have eaten harsh foods, breaking them down to a form the rabbit’s gut can easily absorb.

You might think that animal coprophagy would lead to diseases and parasites, but the nutrition gained vastly exceeds the possible infection for many animals. Capybaras eat their own feces, so you can’t call it waste. An interesting fact is that lab rats eat up to 40% of the poop from other rats and even themselves. If lab workers prevent them from doing that, they become sick from vitamin B12 deficiencies. Insects such as dung beetles survive on animal dung.

Recycling poop gives evidence that God designed the animal world so food is not wasted. Meanwhile, humans are guilty of wasting food, leaving many people to starve. That is why Jesus Christ, in Matthew 25:35-46, told His disciples to give food and drink to those who are hungry and thirsty.

There is a great story circulating about a man named Jesse Newton who lives in Arkansas and has a dog. He also has a robotic floor-cleaner called a Roomba. The Roomba is a device you program to run while you are in bed, and it goes all around the rooms you designate sweeping up any dirt and debris on the floor. Last fall Mr. Newton had his robot programmed to clean his house starting at 1:30 AM.

The Roomba was doing fine until it hit a pile of dog poop that was picked up by the brushes and wheels of the device. The robot then spread the feces all through the house, on the carpets, the floors, the chair legs, the baseboards, and the kids’ toy box. Mr. Newton tells the whole hilarious story of how he discovered the mess at 3:00 AM and how he spent the next three hours trying to clean it up. He said the Roomba left the house “looking like a Jackson Pollock poop painting.” The story went viral on Facebook and was picked up by many news agencies, newspapers, and their websites, including USA Today and The Guardian. You can Google it to get the whole story.

That story reminded me of articles we have published in the past dealing with the process of cleaning up the waste that accumulates in nature. There are many living things that exist solely on the wastes of animals and plants. A classic example is the dung beetle, which cuts up chunks of “cow pies” or “elephant pies” into small balls and rolls them to their homes underground. Termites process dead trees into fine confetti which helps aerate the soil. Flies produce maggots which process large carrion in such a way that it is returned to the ecosystem in the form of chemicals. Certain kinds of fish clean up the bottom of rivers and lakes. While zebra mussels are a hazard to water-handling equipment, they filter and clean the water of their environment.

The universe is designed in such a way that things are constantly being recycled, cleaned, and worked back into the soil for future generations. This cleaning operation is highly complex and vital to all forms of life. It was not just a series of fortunate accidents that designed and maintains the system. By the way, iRobot, the company that manufactures the Roomba, says that this problem is not uncommon for people who have dogs or cats. Their engineers have been working on “poop detection technology,” but for now, they recommend not using the device when animals that might make a mess are present. We are glad that God figured out the process a long time ago.
