The most common types of piranha include the red-bellied piranha (Pygocentrus nattereri), known for its distinctive red underbelly and aggressive behavior, and the black piranha (Serrasalmus rhombeus), which has a powerful bite and is often considered one of the most dangerous species. Other notable types include the white piranha (Serrasalmus spp.) and the sanchezi piranha (Pygocentrus spp.). These species are primarily found in the freshwater rivers and lakes of South America, particularly the Amazon Basin.
