Blarina Brevicauda is often referred to as the short-tailed shrew or the northern short-tailed shrew. This small mammal is one of the smallest shrew species in North America, ranging in size from 4-6 inches in length. It is a very aggressive predator, known for its ability to kill prey that is much larger than itself. Some other synonyms for Blarina Brevicauda include the Rock Shrew, the Mole Shrew, and the House Shrew. While these creatures may not be as well known as some of their larger mammalian counterparts, they play an important role in the ecosystem and are a fascinating example of the diversity of life on our planet.
