Selenopid Crab Spider (Selenops actophilus) - 1/2-3/4" (Adult WC)

Flat as a sticker, faster than your eyes can track Selenops actophilus, the Selenopid Crab Spider or "Flattie," is a dorsoventrally flattened ambush hunter from the southwestern US and Mexico, pressed thin enough to slide into a crack in the bark and vanish. Under an inch across, it trades size for speed: it delivers some of the fastest strike-and-turn moves ever measured in any spider, whipping sideways in a blur before you register it moved. Set it on vertical bark and it melts into the surface, all patience and stillness, until something small wanders too close. Low-maintenance and beginner-friendly, with venom that isn't medically significant to most people: it wants vertical bark, a sealed lid, and respect for how fast it moves. Feed lightly and let it hunt. Do not try to catch it barehanded, because it is gone before your fingers arrive. The care guide has the full build and the boundaries.
