Although specimens of the “olinguito” had been kept in museums and zoos for decades, the small South American mammal had been misidentified by scientists up until yesterday.
“The story of the olinguito is one of mistaken identity,” said Kristofer Helgen, a zoologist at the Smithsonian Institution. “I first realized this animal existed by finding specimens in museum collections that had been put in the wrong place, sort of identified as the wrong animal.”
The olinguito is a member of the raccoon family, and lives only in the cloud forests of Ecuador and Columbia. After Helgen studied the specimen in museums, he decided to travel to the animal’s natural habitat in South America to find one in the wild. His friend, an Ecuadorian zoologist, served as a guide.
“He knows the forests of the country extremely well,” said Helgen of his friend. “He took us to a place where he thought we would have our best chance. On the first night that we were there, we found the animal in the wild.”
“I travel the world looking for new species of mammals, and I have discovered other mammals new to science, but I consider this my most exciting discovery yet.”
Newly Discovered Mammal Was “Hiding in Plain Sight”
