Question

How do dolphins and whales communicate?

• A. By generating ultrasounds
• B. By using echolocation
• C. Both A and B
• D. None of the above

Answer 1

The correct option is C Both A and B

Echolocation is a technique used by bats, dolphins and other animals to determine the location of objects using reflected ultrasound waves which were generated by these organisms. This allows the animals to move around in pitch darkness, so they can navigate, hunt, identify friends and enemies, and avoid obstacles.

Dolphins and whales make use of ultrasounds to communicate with one another and for echolocation to hunt food and to find objects in their path.

Hence both A and B are correct.
