Curious Minds Did You Know? Sharks have rough skin that feels like sandpaper. This actually helps them glide through the water more easily!
Sharks tooth Fossil. A shark continues to grow and shed teeth throughout its life. Some species shed as many as 35,000 over a lifetime! These teeth are made of calcified materials and if they fall into sedimentary material on the ocean floor, they can become fossilised over millions of years.
Fossils are named from the Latin word fossus which literally means having been dug up. They are the preserved remains or traces of animals, plants and other organisms from the remote past. A fossil normally preserves only a portion of the deceased organism and usually, that portion was partially mineralised during life such as the bones and teeth of vertebrates or the chitinous exoskeletons of invertebrates.
