The Grasshopper mouse has a very surprising evolutionary trait: it can withstand a normally deadly sting from a scorpion.
The mouse, which is native to the American Southwest, has a diet that includes the Arizona bark scorpion. The scorpions sting usually contains enough venom to kill small mammals, but, in the case of the Grasshopper mouse, the scorpion comes up short. The venom actually works as a pain killer instead of a pain stimulant for the mice.
Using this information, MSU-led research could lead to advances in treating pain in humans. Check it all out in the video above.
