Sawsharks are very interesting creatures. There’s a point out of their mouth that has sideways teeth on it. It cuts it’s food up with those teeth then eats it. Sawsharks are related to an extinct shark that also had weird looking teeth. It’s name was Helicoprion and it’s teeth make a circle on the bottom lip of the sharks mouth. There is a debate about where the teeth actually were, but I think that it is on the lower lip, not inside the middle of it’s mouth.
This picture was from the Aquarium of the Pacific. My dad took this. You can go there too, to see all kinds of different sharks.
