¿Por qué algunos animales no tienen orejas?

The video explores how different animals detect sound. While human ears are designed to capture sound, owls have even more sensitive hearing. The desert fox has large ears relative to its size, but some animals like snakes don't have visible ears. Snakes sense vibrations through their jaws, which are transmitted to their inner ear and brain. Insects also detect sound through various body parts, such as caterpillars using body hairs, ants using antennae, and grasshoppers using tympanal organs. The video concludes that animals have evolved diverse methods to detect sound, even without traditional ears.
