I forgot about one new critter, likely because it's my husband's and I may or may not be somewhat terrified of this particular critter.
This is Sir Lawrence of Arabia, regardless of actual gender. The deli cup just said "Bark," but my husband thinks this is a little Arizona bark scorpion, so we've set up the tank accordingly. It ate some crickets, which was really cool, but also really horrifying to watch. It chased them around the enclosure and then stung them.
What a weird creature. Enjoy!
