what is the average time it would take for a school of 100 parana to strip a mans flesh down to the bone?

Question

100 pirana(flesh eating amazonian fish)

Answer 1

depends on the size of them .some are large some are quite small.///////////////

Answer 2

Its a very well known and documented fact that pirranha fish (or however you spell it) goes around in relatively small groups of about 40-50 specimens. So in order to answer your question, lets assume that two groups of 50 get together, bury their rivalry and bloody river-sharing battles, and decide to work together. Two schools of pirranha fish with one school of thought. So some silly person conveniently falls into their river, and they all look at each other, nod their fishy heads as one, and start feasting. If the person is thin, then it will probably take just a few minutes. If the person turned out to be whacko Jacko, then there would be probably very little truly edible parts to him, so the Pirranha would give up, look for someone to blame, the two schools would divide and trouble would be a foot (or a fin). If however, the person was a large-breasted blond, then the two schools would probably line up in a fashionable way, and take their time eating her one by one.

Answer 3

There are about 40 species of piranha. In the local Amazonian Tupi language, the word means "toothed fish". They range in length from a few centimetres up to 60 centimetres. They do indeed have fearsome pointed triangular teeth. A few of the species are vegetarian, but most of them eat meat. Most of the species of meat-eating piranha will simply "graze" off other fishes, taking a single small semi-circular bite out of a fin or scale, before letting the wounded fish swim away. Each fin or scale is between 35% and 85% protein, making it very nutritious. The fin or scale of the victim will grow back in a few weeks, so that the piranha can have another go. But only about three species (especially the red-bellied piranha) show any real signs of aggression.

In general, the carnivorous piranhas prefer to graze or scavenge off dead animals, rather than attack a whole healthy animal. The Brazilian scientist, Ivan Sazima, in many years of research, did not find one single case of piranhas killing a human. However, his team found only people who were already dead in the water, before the piranas came along. They found that one person's drowned body had been reduced to bones - but that was after four days in the river. Another person's drowned body, after 20 hours in the water, lost the flesh of the arms and legs, but not the trunk. A third person, who had died from a heart attack in the water, lost only small amounts of flesh after a few hours in the water. In no case, was it like in the James Bond movies, where the unwanted villain has every shred of flesh torn from him, as he vanishes into the foaming water.

However, there are a few certain rare cases where the piranhas (usually the red-bellied ones) will actually "make the water boil".

One situation is when the local fishermen will deliberately throw unwanted fish guts into one small part of the river. Over time, the piranhas migrate to where the eating is good, and will quickly demolish (for example) a plucked dead chicken, if you throw one into the water. These piranhas have been conditioned to eat bleeding guts, and will go into a feeding frenzy over a chicken. But just a few hundred metres upstream, a different bunch of piranhas (who have not been conditioned) will not get so excited over a plucked dead chicken.

Another situation where the water "boils" with voracious piranhas is where a whole bunch of birds have their nursery in a tree that overhangs the river. As the parents vomit up the food for their babies, some of it drops out of their mouths into the river - and the piranhas learn to hang around for this Free Food From Above. Once they have been conditioned to eat this Free Falling Food, these piranhas will attack any baby bird that drops into the river below.

Another situation where you should be cautious is when you have just caught a piranha, which is now flapping about in the bottom of your boat. This piranha is quite annoyed, and it's probably better to keep away from it. This is not the "water-boiling" situation.

But in general, apart from these few specific cases, piranhas are harmless to humans, who happily swim in the same water as them. Richard Conniff, in the July 1999 issue of the Smithsonian, describes how he swam with them - both in a tank in Dallas, and in the Amazon rainforests - and came to no harm.

So with the piranha, their bark is worse than their bite.

Answer 4

Piranhas generally pose no threat to humans. Natives frequently swim in piranha-infested water without attacks or scratches. However, it is not recommended to swim where piranha live in drought season because of increased aggressiveness caused by food scarcity and increased tendency to form large schools. Piranha fish also have the same sensory system that enables sharks to detect blood in minuscule amounts, so it is believed that swimming with an open cut may enhance the chance of an attack, yet Piranha fish rarely try to eat animals much larger than themselves.

Answer 5

they
(a schoal much smaller than 100 fish) can strip a full grown capabara in less than 30 seconds.i think it would probably take less than 2 minutes for a group that large to strip a man of 250lbs to the bone.

Answer 6

About 15 minutes.

I've never seen this happen with a humans only with animals.

I've seen them eat a big pig in less than a minute.

Normally a school of pirai would be more than a hundred.

Answer 7

It depends if they've just eaten and the weight of the man, but they're deadly and vicious and they strip him to the bone really fast so never swim in piranha infested water or we'll miss you!!

Answer 8

One... you spelt pirahna wrong XD
Two... I would imagine a matter of seconds, or at least that's what a movie said about them in my Geography class while we were studying the Amazon...
I'd go with that lengthy answer, though XD

Answer 9

If it was a fat man it would take 5:32sec.If it was a thin man it would take 2:49 sec.,depending on if they just eat are not..

Answer 10

3 TO 4 MIN

Answer 11

5 hours if it was a yank!! 2 secs if a Belsen boy
