Question

Which of the following senses is most important for dolphins to capture their prey?

• A. Sense of sight
• B. Sense of smell
• C. Sense of hearing
• D. Sense of touch

Answer 1

The correct option is C Sense of hearing

$\bullet$ Dolphins use their strong sense of hearing to capture their prey.
$\bullet$ They make high-pitched squeaks known as ultrasound which humans can't hear.
$\bullet$ The ultrasound reaches the prey and bounces back to the dolphins, and they are able to locate the prey. This is also known as echolocation i.e., locating using echoes or sound that bounces back.
