The Southern grasshopper mouse is a small rodent that lives in deserts and dry steppes of North America. Unlike most mice, it hunts insects and even other small animals.
The Southern grasshopper mouse differs from other mice by its predatory lifestyle and ability to eat scorpions. It helps control insect populations in the desert and serves as food for snakes, owls, and foxes.
Hunts at night, runs quickly and bites prey with sharp teeth.
