New whipray species identified by its DNA

[unable to retrieve full-text content]Biologists have analysed tissue samples of 115 spotted whiprays of the Himantura genus, collected in various parts of the Indio-Pacific region. By means of genetic markers -- as opposed to morphological criteria only -- the scientists were able to describe these leopard-skin whiprays in detail and demonstrate that they are isolated from each other in terms of reproduction. They have also discovered a new species that they call Himantura tutul, which belongs to a genetic line that is totally distinct from the three other species that are known in the same group: H. leoparda, H. uarnak and H. undulata. They frequent the same costal habitats but occupy different ecological niches.
