The colour of an egg depends on the colour of the hens ear lobe! Hens with white ear lobes lay white eggs. Hens with red ear lobes lay brown eggs. Rhode Island Reds, New Hampshires and Plymouth Rock chickens lay brown eggs. White Leghorns and Brown Leghorns lay white eggs.

The average ear of corn has 800 kernels, arranged in 16 rows.

Cats have amazing hearing ability. A cat's ear has 30 muscles that control the outer ear (by comparison, human ears only have six muscles). These muscles rotate 180 degrees, so the cat can hear in all directions without moving its head.

A cat has 32 muscles in each ear.

The little lump of flesh just forward of your ear canal, right next to your temple, is called a tragus.

When a Hawaiian woman wears a flower over her left ear, it means that she is not available

The smallest muscle in the body is located in the middle ear, the stapedius is a miniscule 1.27 millimeters in length. It controls the tiniest bone in the body, the stapes or stirrup bone. The stapes and two other bones conduct sound vibrations through the middle ear. The stapedius is innervated by the facial nerve (VII).

Only 1/3 of the people that can twitch their ears can twitch only one at a time.

Your ear bones are the smallest bones in your body.

The ear bones are named the hammer, anvil and stirrup. You can see that a trip to the blacksmith was probably a common occurrence for the person or people who originally named the bones!

Tinnitus is a condition where a person hears sounds that appear to come from inside the head. In many cases no cause can be identified, and the sounds can be so distracting they keep the sufferer awake at night.

Many animals have muscles which can move the outer ear, so ears can point in different directions. This ability is virtually non-existent in humans.

Sound can also be conducted to the inner ear through your skull and its contents. Usually you hear your own voice partly through your head like this and partly through the air, which is why your it may sound strange to you on a tape recording in which all the sound will have travelled through the air.

Hearing impaired people may be assisted by hearing dogs, which will usually have a brightly coloured collar and lead.

The ear also contains semi circular canals, structures which help us to balance.

Snakes lack a middle ear and so 'hear' by sensing vibrations along the ground.
