Elephant Shrews Aren't "True" Shrews
When they first discovered sengis, biologists (understandably) grouped the small mammals in with shrews. They named them elephant shrews because of their long noses, which resemble an elephant's trunk. However, molecular evidence has prompted modern biologists to put elephant shrews in the superorder Afrotheria, which also includes elephants, dugongs, hyraxes, and aardvarks.
