Q:

Do sharks make noises?

A:

Sharks do not have specialized organs for producing sound, so any noise a shark makes is an unintended product of its daily life, such as when it swims or eats. The draughtsboard shark can inflate itself and produces a barking sound when it fills with air instead of water.

    What are sharks afraid of?

    A:

    Sharks are afraid of dolphins when outnumbered because they like to eat animals that are much smaller than them, including baby dolphins, but adult dolphins will protect their young by trying to kill a shark any time they see one. Dolphins are usually successful at killing the sharks that they find because they attack in groups, ramming their bodies into the shark until it dies.
