Sounds Fishy

Lured to a microphone by a pinch of fish food, a striped burrfish sounds off in a 1945 experiment on fish noises. Many fish grunt, purr, drum, croak, and even grind their teeth. This one doesn't vocalize through its lips but rather by grinding its teeth to show distress, aggression, or to attract a mate.
