- Young piranhas hide among the stems and roots of water plants.
- During the dry season, adult piranhas “disappear” from many of the smaller waterways. It is believed they head to deeper water until the rainy season returns.
- As streams and ponds dry up, smaller piranhas are forced into tight quarters with one another. Here they may attack each other.
- Piranhas are attracted to the smell of blood and frantic splashing like that of an injured animal.
- Piranhas in large groups may leap into the air during feeding.
STATUS

POINTS OF INTEREST

- Piranha upper and lower jaws fit together like scissors, shearing off chunks of meat which they swallow whole.
- They often swim in one direction at the same time, avoiding having another piranha directly behind.
- Piranha will bite each other in a feeding frenzy.
