Think of the smallest mammal you can imagine. A hamster? A mouse? Maybe even a tiny rat? Well — you’re not far off! Recently, scientists discovered a mammal even smaller than many of those animals. In the mountains of Ethiopia, researchers identified a new species of shrew called Crocidura stanleyi, which is now considered one of the smallest mammals in the world.
This tiny mammal weighs only about 3 grams, which is roughly the same as a sugar cube. Its body measures just a few centimeters long, making it incredibly small. Because of this, it can hide easily in grass, soil, and leaves.
This discovery was made in the Ethiopian Highlands, where scientists were conducting field research on small mammals. They used pitfall traps, small containers placed in the ground, to collect and study animals living in the area. After carefully examining several specimens and conducting genetic testing, researchers confirmed that this shrew was a species never seen before. The species was named stanleyi in honor of scientist William “Bill” Stanley, who first collected a specimen years earlier.
Like other shrews, Crocidura stanleyi has a pointy snout, pin-sized eyes, and tiny ears that are partly hidden by its fur. These features help it move through tight spaces and search for food underground. Even though detailed studies about the species are still ongoing, scientists believe it eats insects, worms, and other small invertebrates. Shrews have extremely fast metabolisms, meaning they must eat frequently to survive.
The smallest mammal, discovered early this year, is smaller than you imagine! Who knows, there might be even smaller wonders hidden deep within nature.
