genus phrynicus | the whip spider, or “tailless whip scorpion” (which sounds arguably more badass than whip spider) is actually harmless to humans, save for the brief jump scare from happening upon it as you arrive home, loaded with questionnaires and bottled water.
despite the name, this guy’s not a spider at all; rather, it’s an ancient arachnid (dating to the carboniferous period), part of the order of “blunt rump” arthropods known as amblypygi. you can see the heavy resemblance to its sea-dwelling, crab cousins. many whip spiders even walk in a crablike fashion.
those large front “arms” are raptorial pedipalps — a second set of chelicerae (“jaws,” or perhaps more accurately “claws”) used for snatching up prey. the long, whiplike front legs are used as antennae.
i think what i find most interesting is that these are nocturnal animals, yet this one graced the guesthouse tile at around 10:30 this morning.
