After 1918, First New River Dolphin Species Discovered in Brazil
For the first time after World War-I, a new river dolphin has been found by researchers in Brazil. There are a total of only five species, including the latest discovery, of this kind across the world. Out of already known four species, three are listed as critically endangered.
The researchers are of the view that the newly found dolphins are related to Amazon River dolphin, which are known as the most intelligent river species.
Based on the river where it was found, the dolphin has been called as Araguaia. "It was something that was much unexpected, it is an area where people see them all the time, they are a large mammal, and the thing is nobody really looked. It is very exciting", said Dr. Tomas Hrbek, lead author of the Study, from the Federal University of Amazonas.
A report about this river dolphin has been published in the journal Plos One. According to this report, the species got separated from other river species found in South America about two million years back.
It is expected that nearly 1,000 of river dolphins are residing in the Araguaia river basin at present. The recently found dolphins have long beaks with which they hunt for fish in the mud at river's bottom.
