Do geese have teeth?

Do geese have teeth?
Geese do not have teeth made of bone and enamel, but have serrated tooth-like ridges of cartilage along the mandibles.  These are handy for cutting through grasses and pulling up roots and vegetation from the bottom of ponds.
Geese also have spiky tongues that act like a sieve, allowing the bird to filter food particles from the water.
