New river dolphin

According to scientists a new river dolphin has been discovered. Based on its DNA it is certainly a new species, and the first discovered over the past 100 years. Even though this new dolphin is considered to be endangered, it has survived undetected until now. This would seem to indicate that it may not need human protection to continue to survive, and in fact, may be in even greater danger now that it has been discovered. Do you agree with me or do you disagree?

River dolphins (also known as botos) are among the rarest, and most endangered, dolphins in the world. Three of the four known species are listed as "threatened" by the International Union for Conservation of Nature (IUCN). The discovery of a wholly new species—the first such find in a century—is thus exciting news for biologists and conservation officials.
