Sand tiger sharks are my favorite kind of shark because: They have two uteri and produce a lot of eggs, but they only give birth to two pups -- one from each uterus. Thats because as the sharks develop their embryonic teeth, they start to eat the other embryos, killing their unborn brothers and sisters, as well as the unfertilized eggs. Its an embryonic Hunger Games, until only one shark per uterus remains!!! So every Sand Tiger shark swimming around out there is a total beast! Here is a video of it!!! https://youtube/watch?v=ZrqgPjZ07Ts (I watched it with the sound off so if it is for some reason inappropriate, I didnt know.)
