Yes, the creature in your photo is a vinegaroon, also known as a whip scorpion. Specifically, it’s likely Mastigoproctus giganteus, a species found in parts of Mexico and the southwestern United States.
Key Characteristics:
• Large pincers (pedipalps) similar to a scorpion’s.
• Whip-like tail (non-stinging), which is used for sensing.
• Dark, armored body.
• No venom, unlike true scorpions or spiders.
• Defensive spray: it can spray a vinegar-like acetic acid solution when threatened (hence the name “vinegaroon”).
Harmless to Humans:
They do not bite or sting and are generally harmless, though they can pinch if provoked. They’re beneficial because they prey on insects and other pests.
Habitat:
Vinegaroons like humid, dark environments and often come out at night. Finding one in a freshwater stream in Jalisco is not unusual—they sometimes wander into moist areas during hot weather or after rains.
