Stupid Question

My last stupid question: flys n lung cancer, was fairly stupid, but this is quite a good one.
You know the phrase "sweating like a pig"? Well some of you might no it. Anyway I was getting sick o saying it, so I say loads o different animals. N today I said "like a fish".
Question:
Do fish sweat???
If so how can you tell???
There in water.
This has me puzzled, thought it might be intereting to see what you guys think. You normally have something good to say.
I know I havent posted for ages but I been busy. Still rockin hard tho'.

i doubt fish sweat because the water keeps them cool and if the water is so hot they would have to sweat, they would probably die anyway.

Even if the water is hot, arent fish cold blooded, which means they adapt to the climate, or summate. I think they dont sweat. Any other coments anyone? I could be wrong.

i believe every creature(exept single cell and other molecular organisms)sweats on a molecular level at least....sweating is a waste disposal system as well as a cooling proscess....even fish dont crap and pee enough problably......

sweatings is more than just to keep you cool, it gets rid of the toxins in your body.

and alot of fish cant adapt to large changes in temperature, like the walleye can only adapt to like 2 degrees difference (in the water) .

Perhaps.

hey iiholy, your probably the funniest person ive seen on this site.

Pigs don't perspire, neither do dogs and I never have seen a sweaty cat, you might want to just stick with " Sweating like a Horse " for accuracy's sake......

oh yeah, cause dogs cant sweat so they stick their tongue out to cool off.
