Scientists: 1 in 4 Mammals Faces Extinction

The Grey-Faced Sengi (Rhynchocyon udzungwensis), an elephant-shrew from Tanzania, is listed as Vulnerable because it is known from only two areas. It belongs to a group of mammals called Afrotheria that evolved in Africa over 100 million years ago and whose relatives include elephants, sea cows, and the Aardvark. The Grey-faced Sengi was only described this year after being caught on film in 2005 in Tanzania’s Udzungwa Mountains. Credit: F. Rovero, Trento Museum of Natural Sciences, Italy
