Waterfalls?

I believe I read that Aruba is not high enough above sea level to have many waterfalls. Is this true? I love to photograph waterfalls or even just interesting places on the shore where water has eroded the rocks. Are there any in Aruba?

You know I have no idea, I definitely have no memories of waterfalls there, but there are so many other things to photograph. Maybe I just didn't see them. Perhaps if you take a boat trip you'll get to see something interesting.
