We are all different in sizes. Some of us, such as the Spined Pygmy Shark, are as small as sixteen centimetres long. That's the size of a cucumber!

Other sharks can be as huge as twelve metres long - such as the whale shark but we are usually around five metres long; but that's still big; that's the size of a tree!

The biggest batoid, which is the Manta Ray, can grow up to six metres wide! Now that’s probably twice the size of your bedroom- isn't that amazing?
