Do Fish Break Wind? Investigating Digestion in Aquariums

[wolram]

Do fish----

Break wind, when looking at them in aquariums i have never seen bubbles coming from that end, so may be their digestive system works differently.

It is well known that fish have shy bowels. They will not break wind while you are watching.

All seriousness aside, fish don't have much of an opportunity to get air into their digestive system, mostly they get water.

That being said, they do sometimes get air into their systems, especially if they eat at the surface. I ahve seen my poor little neon tetras fighting desperately to maintain neutral bouyancy after a particularly piggish meal. They have to swim straight down vigorously and continuously to stay in one place.

I'm pretty sure that's why baraccuda are so fast; their eating habits give them jet propulsion.

Danger, you are just so far behind, you should be on the ghost cam case by now.

Then whales must have a steam engine:rofl:

Wolram, I watched QI this very evening. Apparently (according to Steven Fry) herrings are the only fish seen to have had bubbles coming out of their anuses. However, he said it wasn't gastric gases, but emissions from the creature's buoyancy bladder.

I read it already; there just wasn't anything for me to contribute. I'd have a shotgun, not a camera, wired into the sound detector.

There was an interesting point on Qi a couple of weeks back which was that kangaroos cannot fart because they have special bacteria in the gut that either neutralise the gases or stop them being produced in the first place. They're hoping to use this to stop cows from emiting greenhouse gasses in an atempt to stop global warming so we can all still use cars.

Sounds good to me.

No, no, no, this tampering with nature has gone to far, can you imagine the taste of meat from a fartless cow, i for one will be out in the field with my placard saying allow cows their flatulence.

1). Where does the carbon in the cow's gas come from?

2). Where did the carbon in that come from?

And then you have to factor in the carbon that went towards making the cow.

I did hear, on the grape vine, that the union of ovbovs were thinking on a
march to London, to protest about humans polluting the countryside.

I keep telling you not to confuse grape plants with telephones. You had better clean out your ear.
