I never fail to be amazed at the amount of new species still being discovered. This discovery is a little more surprising because it was found in New York City. The new leopard frog was found after scientists studying frogs in the area found they had a different call. It was then they discovered the frog was a new type. The frogs are currently found in Staten Island, mainland New York, and New Jersey. It appears they have remained undiscovered for so long, simply because they look like other frogs in the area.
