help identify this critter!
Dear bugman,
My friend took this photo recently during his trip in Costa Rica. He is convinced that it is a "pseudoscorpion," because he has seen photos that match; now I don’t know what kind of pseudoscorpions he’s been looking at because I know for sure this is not it! I am pretty sure it’s a whip scorpion but he would not believe me! Can you please help identify it and settle our debate? Thank you for the awesome site!

Hi Celia,
Common names are always subject to local variations, hence the widely accepted taxonomic system based on genus and species. However, in most circles, you would be considered correct. The Tailless Whipscorpion is a large but harmless creature. The Pseudoscorpion in minute by comparison, often being confused for a small tick.
