Where does the grasshopper mouse live?
Where does the grasshopper mouse live?
Grasshopper mice are found in shortgrass prairies, and desert scrub. Most prefer xeric areas at low elevations. They have a home range of two-three hectares, and are found in low densities.
Where do scorpion mice live?
The southern grasshopper mouse or scorpion mouse (Onychomys torridus) is a species of predatory rodent in the family Cricetidae, native to Mexico and the states of Arizona, California, Nevada, New Mexico, and Utah in the United States.
Why can grasshopper mice eat bark scorpions?
When the grasshopper mouse attacks a bark scorpion, it barely notices the arachnid’s intensely painful sting. Now researchers know why: the rodents have a mutation in the cellular pathway that controls their pain response, making them resistant to scorpion venom.
Why do grasshopper mice seek out scorpions?
Tiny desert-dwelling rodents have found a way to take the sting out of scorpion venom. A protein in the nerves of southern grasshopper mice hijacks the venom’s toxins, silencing pain signals that usually race to the brain when scorpions strike.

Do scorpion eat mice?
Scorpions eat a variety of insects, spiders, other scorpions and lizards. They also eat small mammals, such as mice. Scorpions must have water to drink, but they can survive for months without food. Scorpions use their pincers to capture and crush prey.
Do grasshopper mice eat scorpions?
There’s a new contender for the most badass mammal: the southern grasshopper mouse. This little creature from the south-western USA attacks and eats bark scorpions—a group of large arachnids, whose stings are incredibly painful and often fatal.
Can scorpions eat mice?
What are the primary benefits of the grasshopper mice adaptation?
By developing an adaptation that not only negates the usually painful venom of its main prey, but produces a pain-relieving effect, the grasshopper mouse uses the scorpion’s venom to its own advantage in a fascinating counter-attack in the evolutionary arms race.
What kills a mouse plague?
Farmers are currently using a chemical called zinc phosphide to poison mice in paddocks. The inorganic compound is coated on wheat to turn the grain into the bait. That poisoned grain is then scattered around pastures, with a single grain providing a lethal dose to an adult mouse.
How are bark scorpions and grasshopper mice related?
Fortunately, due to their ability to maneuver well, they are able to move quickly in narrow areas allowing them to capture their prey more efficiently. The bark scorpion and the grasshopper mouse have been coevolving with each other so closely that it has affected their physiology.
Is the grasshopper mouse immune to scorpion venom?
The grasshopper mouse is known to be immune to various venoms released by its prey (scorpions, snakes, etc.). Grasshopper mice are nocturnal and avoid exposure to bright light.
How does a grasshopper mouse defend its territory?
It also stalks its prey in the manner of a cat, sneaking up quietly, and defends its territory by “howling” like a small wolf. The grasshopper mouse is known to be immune to various venoms released by its prey ( scorpions, snakes, etc.).
How big does a southern grasshopper mouse get?
The southern grasshopper mouse has around a 3.5 to 5.0 inches (8.9–12.7 cm) long body and a tail that is generally 1.0 to 2.5 inches (2.5–6.4 cm) long. Its behavior is rather distinct from other mice. It is a carnivorous rodent, dining on insects (such as grasshoppers), worms, spiders, centipedes, scorpions, snakes, and even other mice.
