I wouldn't know, though I would question the idea of a piranha smelling under water. We tend to mean smell when we inhale an odour, if we tasted something in water that would be taste and since fish evolved in water they shouldn't have any sense of smell I shouldn't think! It would be a question of taste.
both can be as dangerous as they attack when they smell blood in the water. However as piranhas hunt in groups of up to 20 i believe piranhas are more dangerous.
Sharks all the way.
Piranhas are generally not aggressive unless provoked or in certain situations, such as during feeding frenzies. While they are known for their sharp teeth and strong bite, they typically do not attack unless they sense a threat or are hungry. The presence of blood can trigger a feeding response, but they may also bite if they feel threatened or if they are in a competitive environment. Overall, piranhas are more likely to avoid confrontation unless they are motivated by hunger or stress.
Piranhas do not just attack people for no reason. They may go into a feeding frenzy at the smell of blood and they will attack if they sense frenzied movement like that of a fledgling bird falling into the water. Really they, like many animals, can find much easier prey than humans so attacks on humans are rare although they do occasionally happen when water levels are low.

Piranhas can sense movement in water not just the smell of blood. Although their primary food source is fish, they also will attack mammals and birds who are swimming or standing in water. The teeth of a piranha can slice through bone and within minutes they can consume an animal the size of a pig. There are four different species of piranha thought to be dangerous to humans and there are also many accounts of fatalities.
no piranhas do not attack people they just eat the meat
if approached at all, may attack.
The piranha is known for its keen sense of smell, which helps them to locate prey. Blood in the water will send piranhas into a frenzy. They are also able to sense any unusual vibrations in the water around them and any commotion in the water will attract a shoal of piranhas.
Piranhas only attack when hungry or threatened
Sharks smell blood so they go after it and because of mucky water or not clear water and/or because the bad sight sharks have,they attack what is in the area of blood
They are racist to humanity. and they might be evil..
