Two of the Zoo’s black and rufous giant elephant-shrews, or sengis, had a little baby elephant-shrew several weeks ago, but zookeepers in the Small Mammal House only announced they discovered the animal late Friday. Zoo biologist Ashton Shaffer, in this Flickr video, described the birth as rare, although the two parent elephant-shrews the Zoo acquired from the Philadelphia Zoo in 2007 have had at least four offspring since they arrived in D.C.
