Scientists have just discovered two new species of fresh water stingrays in the Amazon rainforest near the port city of Iquitos, Peru. These two stingray species both look like pancakes with noses. The two "pancake" species belong to the first new stingray genus found in the Amazon region in more than two decades. They also represent just the fourth neotropical stingray genera. In addition to their pancake-like appearance, both rays are big, have slits on their bellies and a tiny spine on their tails.
