The Northern Grasshopper Mouse is a highly carnivorous rodent that hunts and kills large insects, scorpions, and even other rodents, making it unique among North American mice. It is immune to the venom of the Arizona bark scorpion, a trait that has attracted research into novel pain management compounds. Males throw their heads back and emit a high-pitched howl to advertise their territory, earning them the nickname 'the tiny wolf.'
