animals not having ears can still hear how
Dear student
Let us take an example of spider.
Spiders do not have ears. Latest research on spiders show that the hairs on spider's legs are very sensitive.
They can detect human speech from several metres away.
Birds do not have external ear. Their round shaped head helps them to identify sounds from different angles and elevations.
Snakes do not have external ear. They pick up sound waves through the air. The skull vibrates when a sound wave hits it. These impulses move directly from the skull into the snake's inner ears, where the vibrations are sensed by the brain.
