How does a black marlin protect it self?

Black marlins protect themselves primarily through their speed and agility, allowing them to evade predators. They are capable of swimming at high speeds, reaching up to 82 miles per hour, which makes it difficult for larger predators to catch them. Additionally, their sharp bill can be used defensively to slash at threats, and their large size can deter some would-be attackers. By utilizing these adaptations, black marlins effectively navigate their environment and minimize risks from predators.
