You Know I Make You Smile

This only happens when they're extremely hungry and can't detect other fish and animals to dine on. Similar their feeding habits, whether or non these mysterious fish smiling is also a topic for debate.
Where Do Piranhas Alive?
Unless you live in Due south America, you're not likely to encounter a piranha in the water. Most of them live in freshwater lakes and rivers. While they're mostly constitute in the Amazon River, they too inhabit the Orinoco River Basin in Venezuela upwardly to the Paraná River in Argentina. These fish play a vital role in local ecosystems, keeping the rivers on the continent make clean by eating ill and injured animals.
Studies have shown that piranhas have lived in Due south American river basins for tens of millions of years. Whatsoever type of piranha plant in the wild exterior of South America is likely an exotic pet that someone released into a larger body of water.
While near piranhas adopt to eat smaller fish, insects and mollusks, legend has it that when these tiny creatures assail, they can rip big portions of mankind from a human and accept even attacked cows in the past. But Popular Science reports that it would take 300 to 500 piranhas to rip the flesh from a 180-pound human in 5 minutes. Some species of the fish are total vegetarians and simply feed on plants, basics and fruits.
Smithsonian Magazine has credited U.S. President Theodore Roosevelt with spreading the legend of piranhas' supposedly monstrous beliefs. After touring South America in 1913, he wrote, "They are the almost ferocious fish in the globe. Even the most formidable fish, the sharks or the barracudas, usually attack things smaller than themselves. But the piranhas habitually set on things much larger than themselves."
Roosevelt also reported watching piranhas devour an entire moo-cow in mere minutes. Still, the reason for their hunger has been debunked — sort of. At the very least, it doesn't represent typical piranha behavior.

While it may seem like a piranha is smiling, happily pending its side by side attack with a sinister smile that rivals the Joker's, in reality, the fish are adequately shy and laid dorsum. They're mostly scared of humans and prefer not to exist startled. Those that live in the Amazon seem to merely attack people during the dry season when other sources of food are scarce and they're desperate for a meal.
If you opt to swim in an area where piranhas live, avert splashing around if you lot don't desire to get bitten. When the fish can't find other food sources, they may wait for basics and fruits to drop into the water and mistake your hand or foot for 1. Like sharks, piranhas can also odour blood well — a single driblet in upwards to 200 liters — so don't swim if you have an open wound.
