Scientists in Brazil have found a river dolphin species for the first time since 1918 Utah People's Post reported Thursday.
"In science you can never be sure about anything," Dr. Tomas Hrbek lead author of the study said in the statement The People's Post reported. "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," Hrbek said in the statement The People's Post reported. "It is very exciting," Hrbek said in the statement The People's Post reported. "We looked at the mitochondrial DNA, which is essentially looking at the lineages, and there is no sharing of lineages," The People's Post reported.
The endangered species is named Inia Araguaiaensis, and is located in Brazil's Araguaia-Tocantins River system different than its Bolivian river dolphin counterpart, which lives in the Amazon River Basin The People's Post reported.
The change leads scientists to believe the distinctiveness is a result of waterfalls, rapids, and additional elements The People's Post reported.
Inia Araguaiaensis is the fifth of its kind, three of which sit on the International Union for Conservation of Nature's Red List The People's Post reported. Six hundred to 1,500 river dolphins are believed to reside in the water area.
The Inia Araguaiaenisis resembles the Bolivian, but its different brain size sets it apart The People's Post reported.
The two species are not known to produce together according to the study printed in the Public Library of Science One journal The People's Post reported.
Scientists are concerned that the Aaguaian boto dolphin will not stay alive due to a lack of variety in the types of river dolphins in the water, and progression of people.
The Amazon River Basin, is the second river in length, and is slightly smaller than Egypt's Nile River according to About.com.
