The photograph below is an x-ray of a freshwater stingray species discovered in 2011 in the Amazon rain forest. The discovery was made by the research team of Nathan Lo...vejoy, a biologist at the University of Toronto in Scarborough; and Marcelo Rodrigues de Carvalho of the University of Sao Paolo in Brazil. The new species is known as Heliotrygon gomesi. Besides the flat round appearance, the ray is big, with slits on its belly and a tiny spine on its tail. The stingray discovery was detailed in the Feb. 24, 2011 edition of the journal Zootaxa.
