How does a blue whale protect itself?

Echolocation

Blue whales use powerful sonar-like clicks to navigate and find food. These clicks allow them to detect predators and obstacles.

Size: Blue whales are the largest animals on Earth, and their sheer size can deter predators.

Speed: Blue whales can swim quickly, reaching speeds of up to 30 miles (50 km) per hour.

Flippers: Blue whales have formidable flippers that they can use to defend themselves against potential threats.

Fluke: The fluke, or tail, is a powerful tool in the blue whale's defense. Blue whales can deliver devastating blows with their tail flukes that can cause serious injury to predators.

Group Behavior: Blue whales often travel in pods, which can help protect them from predators that target lone whales.
