Genus Cryptotis refers to a group of small, insect-eating mammals known as shrews. There are several synonyms for this genus, including the names Cryptotis parva, Sorex parvus, and Nesiotatrailia. These small mammals typically have pointed snouts, tiny eyes, and small ears which are almost hidden by their fur. They are found across North, Central, and South America, and are commonly found in wooded areas near water. While they are not often spotted by humans due to their small size and elusive nature, they play an important role in their ecosystems as an important food source for predators like owls and snakes.
