Southern Grasshopper Mouse attacks Uropygi, his strong jaws muscles set to crush the arthropod's exoskeleton!! #2026MMM #2026mmm

pixel art of a vinegaroon in dorsal view. it is black with large pedipalps, 8 legs, and a whip-like "tail" at the end of its abdomen.

This scorpion is one of the few known to survive a Grasshoper Mouse attack! Uropygi discharges his vinegarish spray at Grasshopper Mouse, who jumps back in alarm, pawing at his muzzle to deal with the odor (Eisner et al 1961). And Uropygi has more spray in reserve!! #2026MMM #2026mmm

BUT Southern Grasshopper Mouse isn't giving up! Blitz charge pounce, Grasshopper Mouse uses his short legs to pin Uropygi against a rock & and then pins Uropygi onto the ground, placing rodent feet to hold the arachnid in place and... (Langley 1981) #2026MMM #2026mmm

Meanwhile Uropygi is in the Chiricahua Mountains, Arizona, has begun his nighttime search for a meal. #2026MMM #2026mmm

Uropygi surveys his surroundings and his legs tell him he is out in the open! Uropygi runs quickly in between rocks & begins to use his claws to dig in dirt to excavate a burrow, which it will use to avoid the sun in the daytime #2026MMM #2026mmm

Southern Grasshopper Mouse rapidly delivers debilitating bite to the TAIL and lethal bite to the HEAD of Uropygi, dispatching his prey! #2026MMM #2026mmm

Invertebrates are awesome!

This friend is a Vinegaroon. She is an arachnid and uses the first pair of legs like antennae to sense her environment and large, heavy claws (pedipalps) to snare prey. They can spray a vinegar smelling chemical to deter predators.

A large arachnid that looks like a brown lobster with a thin tail. It is standing on my hand with buildings and a mountain ridge in the background.

When Southern Grasshopper Mouse is done eating, ALL that remains of Uropygi are "several appendages and the posterior ventral portion of the opisthosoma with the glands." (Eisner et al 1961) #2026MMM #2026mmm

The 50 cm Uropygi, also known as a whip scorpion, has a mostly black body, w/ four pairs of legs & long skinny tail. (Barrales-Alcalá et al 2018) #2026MMM #2026mmm

Redwing post-bathing feather care.
Notice how the bird occasionally turns & picks-up oil from the preen gland, (uropygial gland), at the base of the tail.

amblypygid, sometimes called tailless whip scorpion (whip scorpions are uropygi/vinegaroons)

But Mouse has spotted quick movement of Uropygi & chases it, giving off little squeaks (sorta like a barking terrier). Mouse eats lots of scorpions (w/ a stomach adapted to deal w/ sharp edges of masticated exoskeletons) so he isn't really worried about this fella(Rowe & Rowe 2015) #2026MMM #2026mmm

Whip scorpions are actually spiders (Uropygi). They are carnivorous, nocturnal hunters feeding mostly on insects, millipedes, and even scorpions. Relatively harmless to humans although they secrete a terrible smell if threatened. #LifeInAThaiForest

The lab is delighted to release the first genome for the giant American vinegaroon! The slowly-evolving order Uropygi captures the strongest signature yet of the arachnopulmonate whole genome duplication. #biodiversity #genomics
