The farts of the animals

"Amazing things about animal flatulence" is the name of a new book by Nick Caruso and Dani Rabaiotti. It ranges from manatees that let go of gas in order not to sink to coral snakes that make enemies flee with loud farting. Air in the stomach is not only known to people.

Fascination fascination

There is hardly a biological topic that excites children more than the question of which animals why, how loudly and how smelly. Nick Caruso from Blackburg and Dani Rabaiotti from London started with the simple question of whether "snakes can fart". The immense interest in this question on Twitter was the trigger to make a book out of it.

Flatulence research

Animal puppies are not only suitable to entertain children, but also an important topic in biology. Adriana Lowe, a biological anthropologist at the University of Kent, said: "Animal nutrition and digestive systems are an important and fascinating field of research, and gas is part of it."

Defense against snakes

David Steen, a wildlife ecologist at Aubum University, explains: "Snakes sometimes reject gases and smells as a defensive strategy, and this is often accompanied by what I would call classic fart noises."

The bang from the sewer

Arizona's coral snake sucks air into its sewer and expels it in a smelly bang. The cloaca is the exit for faeces and urine - reptiles have no separate opening for urine and solids. Even poisonous animals like them are going for gas.

Chance to make biodiversity popular?

Stenn sees a chance in the fascination with the farts: "I don't know if animal flatulence issues serve as an important door opener to bring biodiversity to a wider public, but it's always fun to see what attracts people's attention."

Fluttering flatulence

David Benett from the Queen Mary University in London confirms: Bats can pee too. And: "The bigger they are, the harder they honk."

Rats, zebras, reptiles

Rats, zebras and bearded dragons are among the creatures that "let air". Birds, on the other hand, appear to have no biological need to let gas escape from the back exit, and they have no gas-producing bacteria in the gut.

How farts drive global warming

Animal pupa can become a problem. Cow gases form atmospheric methane that promotes global warming. As ruminants, bacteria in the several stomachs of the cattle ensure that the grass is digested. This creates methane gas, among other things, which the animals puff out and belch out. Methane is 21 times more climate-effective than carbon dioxide, and cow's pupa contribute four percent to global warming.

Smelly figs

Lowe, the primate researcher, says of the chimpanzees in the Budongo forest in Uganda that their gas emissions depend on their diet: "Fruit stimulates digestion more than leaves, and figs seem to be the worst offenders." Lowe adds: "I have been with one several times or two chimpanzees on the go and didn't notice that others were around until the fart started. "

Balloon quality

Lowe says, "Some of them are of a very long quality like balloons that let air out, which is convenient because it gives a longer clue to find out where it comes from."

Ping pegs to communicate

Some herrings swallow air on the surface of the water, store it in the swim bladder and release gas through the anal outlet. This creates a very high frequency. These are used for communication in the swarm, and the larger the swarm, the more often the animals puff.

Let air to sink

The sand shark swallows air and stores it in the stomach to get a boost. If he wants to sink to the bottom of the sea, he releases the gases through the rear exit. The manatees do a similar thing: The Caribbean manatees have extra gas stores in the intestine. Like the cows, the vegetarian diet makes their stomach produce methane in abundance. This helps the animals to float on the water surface. If you want to eat in deeper water now, let the gas out. Manatees are also familiar with the bloated belly - if they suffer from constipation, they float on the surface like an inflatable boat.

Why do pupils stink?

The gases that leave our bodies consist of nitrogen, carbon dioxide, oxygen, hydrogen and methane. They all don't smell. Hydrogen sulfide provides for the smell.

Sloths don't fart

Sloths are among the few mammals that do not pup. They digest very slowly, and the resulting methane travels from the intestine to the blood system and gets out through the mouth.
