A dog's or cat's farts are rarely audible, but the odor is overwhelming. I have asked biologists why dogs and cats generally fart silently, and their theories include: My vet tells me that if a cat farts audibly, it could be a sign of pathology. Large herbivorous animals such as cows, horses and elephants, on the other hand, produce vast quantities of relatively non-stinky fart gas.
The farts of these animals are noisy and can go on for astoundingly long periods of time. Cows in particular are productive, in part because they swallow huge amounts of air. They need oxygen in their guts for the various protozoa employed there as digestive aids.
Is it normal for dogs to like the smell of human farts? Question submitted by ahmed Yes, any odor that we find disgusting smells delicious to a dog. Dogs respond to the smell of farts, rotting fish, and carrion the same way we respond to the smell of bacon frying or cookies baking. A dog will often sniff the butt of the farter in order to inhale as much of the odor as possible. I have heard only one story about a dog being disconcerted by a fart.
According to a friend, her brother once delivered a fart so evil that it made the dog sneeze, shake his head, and paw at his nose. That was either an unusual fart or an unusual dog. According to our ichthyologist at the University of Guam, fish flatulence per se has not been studied, although people have investigated fish digestion. They find that although most fish have alkaline intestinal environments like our own, coral-eating fish have acidic intestinal contents.
The acid serves to dissolve coral skeletal material. Coral has the same composition as Tums calcium carbonate. One product of the reaction between acid and calcium carbonate is carbon dioxide gas.
Therefore, it is logical to assume that coral-eating fish fart a lot. The other fish probably fart also, for the same reasons that we do. However, Mike Pulte, a great fish enthusiast, said that he has never seen a fish do it. I asked our ichthyologist if it were possible that fish gas would go into the swim bladder instead of out the anal opening. He said that modern fish have an air bladder that is independent of the gastrointestinal tract. The gas comes from enzymatic activity and not from the intestine.
Older models of fish have their swim bladder connected to the gastrointestinal tract, but it is attached high up, closer to the mouth than to the other end, and these fish come to the surface and gulp air to fill the bladder.
Therefore, we can assume that intestinal gas leaves the fish through the anal opening. We also pondered the possibility of fish making noise via flatulence, but apparently most fish noises are made through belching rather than farting. My goldfish used to do it all the time! You'd see a little bubble come out of his anus and stay there, trapped in the mucus of a long string of poop.
And my opaline gourami does it too. Neither of these are coral-eating fish. I have only owned two coral-eating fish so far, but I have never seen either of them fart. It seems most likely to me that much of this gas comes from air swallowed during eating. Also, goldfish have a very simple digestive system and their food is absorbed inefficiently, so possibly the bacteria have more to feed on? Question submitted by coolBettyann Yes, turtles do fart, and their farts smell incredibly bad, as do the farts of snakes.
In fact, it is my opinion, based on personal experience with reptiles and not on any formal research, that many reptiles use farts as a weapon.
Reptile farts smell so bad that sometimes you can tell that one is nearby in the woods, even on a windy day, before you can see the animal. One day I was hiking through the woods in Arkansas with a friend and I told my friend, "I smell a snake fart. In an article published in the December issue of Discover, "the world's leading expert on snake sounds," Bruce Young of LaFayette College in Easton, Pennsylvania, affirmed that snakes do fart.
The sonoran coral snake and the western hook-nosed snake fart with an audible popping sound when disturbed. Why do horse farts smell worse than people's farts? Question submitted by jawsoccer48 I'm not sure that horse farts smell worse than our farts, but they do smell different. Horses have a different diet from us and different gut microbes, so their farts have a different composition. They also fart more voluminously than humans, and the volume of the gas can be overwhelming if one is unfortunate enough to be near a farting horse indoors.
What kind of animal has the highest worldwide output of flatus? Believe it or not, the animal that wins this honor is the humble termite. Because of their diet and digestive processes with more than the usual microbial assistance , they produce as much methane as human industry.
Termite farts are believed to be a major contributor towards global warming. Is it true that cow farts contribute to global warming?
Recent research has shown that most methane produced by cows and sheep emerges from the mouth rather than the anus. So one could more accurately say that cow and sheep belches are contributing to global warming. New Zealand researchers are investigating methods of breeding methane-free sheep. Is there any kind of animal that doesn't fart? Question submitted by Funsux If we define a fart to be an anal escape of intestinal gas, then it follows that animals that lack intestines or an anus cannot fart.
Most animals possess intestines and an anus, but there are some that don't. These organisms lack true tissues and organs. They have just a few types of cells organized into a bag with holes in it. Water flows into some holes and out other holes. Sponges are so different from other animals that some biologists think we shouldn't even call them animals.
This phylum includes the jellyfish, corals, sea anemones and hydra. Their tissues are organized into a bag with a mouth surrounded by stinging tentacles. Food enters the mouth and is digested inside the bag, after which the leftovers are expelled via the same opening. In effect, the same hole serves as both a mouth and an anus.
Any gas expelled by a cnidarian would be more appropriately termed a belch rather than a fart, since the animal lacks intestines and separate anus. These remarkable animals, who dwell on the sea floor near active volcanic regions associated with mid-ocean ridges, possess no mouth, no stomach, no intestines, and no anus.
Apparently they retain their svelte, worm-shaped figures by giving up on eating completely! They survive by means of a mutualistic relationship with chemosynthetic bacteria that live in their flesh. Anyway, these animals cannot possibly fart. A second category of animals that probably don't fart are animals that live very deep underwater. At high pressures, gas remains in solution rather than forming bubbles. So there is a good chance that all those clams, echinoderms, fish and other animals living near the seafloor don't fart because their farts stay in solution and never emerge as bubbles, even though the animals possess perfectly good intestines and anuses.
Is it possible to leave a brown spot on your pants because of a fart, and if so, what causes it? Judging from what I see when I do the family's laundry, I'd say that the answer to the first question is definitely yes. As for the causes, we must remember that what we call "fart" and what we call "poop" are just end-members of a continuum.
That is, we can have a pure fart, or a pure poop, or anything in-between, depending upon the admixture of the two. If a sample consists mostly of poop with only a small fart component, you get such things as jet-propelled bowel movements and spongy, floating fecal masses you know, the ones that refuse to be flushed down the toilet -- they keep popping back up.
If the sample consists mostly of fart with only a small poop component, you get what is known as "skid marks" or "fart art.
Inadequate wiping leads to elongate marks parallel to one's crack, usually with well-defined edges, whereas fart art is generally more circular and has an air-brushed look. Fart art is most likely to occur if 1 a person is suffering from diarrhea, 2 the person is trying too hard to fart, and 3 the person mistakenly perceives the pressure against his sphincter to be gas pressure rather than liquid pressure.
Again, that last situation is most likely to occur if the person is afflicted with diarrhea. How can we tell when it's only gas needing to come out, rather than something more serious? Question submitted by BSneed Our ability to distinguish between the need to fart and the need to poop is something that we learn gradually in the process of toilet training and early childhood. With the tactile nerve endings in the rectal area, we can actually feel different sensations depending upon what is waiting by the exit.
Of course, sometimes we are fooled, especially if the substance at hand is extremely fluid in nature, and that is when we have the unfortunate accident of venting a squirt of diarrhea rather than an innocent fart. What is the best position for farting?
Question submitted by Dylan That depends on what you are trying to achieve. Years and years ago, I read a novel can't remember which that had a character in it who was plagued with intestinal gas pain. The character would coax farts out by getting down on all fours with her butt in the air, pressing her thighs against her belly. So perhaps this is the best position for farting if you are having difficulty getting them to come out. Back when I was in geology field camp, we would sit around the campfire in the evening and ignite our flatus.
It was a ritual. When a fart was ready to emerge, the farter would announce, "I have one. The purpose was to give the person with the match easy access to the critical vent. Expert farters of my acquaintance often shift their weight onto one leg and lift the other slightly when farting. I assume that this position is adopted less to aid in the farting process than to signal that a fart is imminent.
Why do chicks always deny farting?
