Pa-cu, also known as pacu fish, protect themselves primarily through their powerful jaws and teeth, which are capable of crushing hard-shelled foods. They often inhabit murky waters, allowing them to blend in and evade predators. Additionally, pacu can exhibit schooling behavior, which provides safety in numbers, and they may also use their agility to dart away from threats.
