Dr Rathbun holds the shrew
The mammal has a grey face, a long, flexible snout, a tubby, amber-colored body, a jet-black behind and it stands on spindly legs.
Experts are now going to find out how many of these strange animals exist.
The creature is a type of giant elephant shrew or sengi and lives on insects that it flicks up with its long nose.
“This is one of the most exciting discoveries of my career,” said Galen Rathbun, who was part of an international team which confirmed that the animal was a new species.
As well as having different coloring than any other elephant shrew, the new mammal is much larger, weighing 700g and measuring about 30cm in length.
Dr Rathbun said they were amazing: “They are not like a dog or cat you can interact with – but they are so bizarre-looking and a lot of their behavioral ecology is so unique and interesting, you kind of get wrapped up with them.”
