All known species belong to two genera, specifically Serrasalmus and Pygocentrus. This phenomenon happens only when there’s a lack of food, although piranha schools are well known because of their brutal feeding frenzy. Based on narratives, their prey is consumed by them until just the bones are left, yet this event is very uncommon. Pygocentrus hunt in groups, to be able to protect themselves from natural predators and human beings, however in addition they keep these big schools.
A few of the creatures that frequently fall victim to schools are lizards, birds, amphibians, and crustaceans. In addition they eat land animals that venture in their native habitat. They’re competitive throughout the day and most energetic. Smaller piranha fish hunt mainly at daybreak, while bigger piranha takes their fill in late day or the evening.
Besides its nearly legendary feeding behaviours, possibly the piranha’s notoriety is linked to its notable anatomical characteristic-the razor sharp teeth. The piranha has a powerful and big lower jaw filled with sharp teeth. It’s promptly replaced using a fresh development when one is broken.
Learning exact piranha fish facts helps us comprehend better the fish understood in Venezuela as the “caribe.” They lay their eggs in rivers and the lakes of the tropical rainforest. The fish that is male fertilizes the eggs. The abdomen becomes reddish in colour, while the remaining body becomes lighter when piranhas are spawning. Piranha mating behaviour is like that of fowl. When it’s nesting season, the mature piranhas patrol their land that is spawning to be able to protect the eggs.
Piranha fish and people

For the tourist trade, the entire sample dries beneath sunlight and sells them to tourists as keepsake things.
Swimmers in lakes and freshwater rivers where piranhas are recognized to reside have reported injured or being bitten. However, most of the bloody reports are reports that are exaggerated.
