Grasshopper mice, scientifically known as Onychomys, belong to a unique group of rodents that exhibit carnivorous behavior. These mice have an exceptional ability to prey on insects, arachnids, other mice, and even venomous snakes. They are found in grasslands, deserts, and shrublands of North America. Some common synonyms for grasshopper mice include hopping mice, kangaroo mice, and jumping mice. The name hopping or kangaroo mice comes from their ability to jump exceptionally long distances with their powerful hind legs, while jumping mice refers to their energetic and agile movements. Although small in size, grasshopper mice are fierce predators and an important constituent of their ecosystem.
