THE CROCODILE ROCK
Pay close attention the next time you play a Bach concerto to your pet crocodile. If you look closely, you might just see him tapping his toes to the rhythm.
It is true. Crocodiles react to the complex frequencies heard in music such as classical music. This means that, just like mammals and even fish, they have a hierarchical way of processing sensory stimulus, enabling them to navigate their way through the world they live in.
