Fun facts
Its legs are very strong and end in little claws, so it can hold on tight in the wool.
A mother ked does not lay eggs. She grows one baby at a time inside her body and feeds it with a kind of milk.
The baby turns into a hard, dark case glued to the wool. About three weeks later a new ked climbs out.
If it falls off its sheep, a ked can only live for about a week.
Farmers can get rid of many keds just by shearing the sheep's wool.
