One of its favorite prey is the Arizona bark scorpion (Centruroides sculpturatus) — whose venom is potent enough to kill humans.
To get around this, the southern grasshopper mouse reduces the venom’s effects by shutting down the chemical channel that transmits the pain signal to the brain when that particular venom is present. This means they are essentially numb to the pain — although researchers still don’t know why the toxin isn’t lethal to them.
