Your face is the front part of your head. Your eyes, nose, mouth, chin and cheeks are all on your face. It is not just humans that have faces. The picture is a gorilla's face.
Fangs are large, pointed teeth that meat-eating animals like dogs and cats have. Unlike tusks, fangs don't usually grow out of the animal's mouth.
While people and animals are covered in hair, birds are covered in feathers. Feathers are very light and the feathers in a bird's wings are especially designed so the bird can fly.
A fin is a fish's limb. Fish have fins instead of arms, legs or wings. Fish can have a lot more than just four fins. Fins can also be used to describe any small fin-like object that is used for stability, like fins on a boat or an aircraft.
You have four fingers on your hand and one thumb. You use your hands to hold things, and your fingers to make things.
Your fingernails are the hard parts on the back of your fingertips. Your fingernails protect the ends of your fingers from getting damaged. Some people grow their fingernails very long, and paint them in pretty colors.
If you look closely at the ends of your fingers you will be able to see lots of small lines in your skin. Whenever you touch something, the oil on your skin means you leave a mark of these lines, called a fingerprint. Everyone has different fingerprints, and at a crime scene the police will be looking for fingerprints so they can try and find out who was there.
You make a fist with your hand when you close your hand up tight and tuck all your fingers in together. People often make fists when they are angry and want to punch someone.
