Sheep
There are about 1 billion sheep on our planet, with at least 900 breeds of sheep. Sheep don’t have any upper teeth - they do have 8 bottom teeth though. A baby lamb can identify its mother by her bleat.
Sheep have poor eyesight but an excellent sense of hearing. Sheep provide us with meat, wool & leather. Lanolin is natural oil found in the sheep's fleece. It is used to make cosmetics & candle wax.
