shark in their own teeth

your aunt is right^^ i heard about it before. it sounds really strange. i watched that movie too. i liked it^^ i like to watch programs about sharks. past month i watched a movie called the reef. it is about people that got lost in the sea and they were followed by a shark. it was based on a real story. it was really scary.

Well they dont always eat them. They do fall out. And after they do more grow it its place. And are stronger.

Its containt lot of minerals, its good for the bones and teeth. Lot of animal eat part of their bodies that unused again. Some of them eat something to help their food process. Like chickens and birds, eat little stone.

maybe that true. they are a carnivores animals even the baby shark eat their sibling while still inside the mother womb. see they do not recognize even there own blood they would eat them until she only one survives. there are possibility they eat there teeth or lose it, because they bite many things including fish, humans and other debris found in the sea.
