Myrmekiaphila spp., teased into emerging from its burrow at night. As you can see, her fangs are quite visible in this shot. It must be said that Trapdoor Spiders of this kind are typically very timid, preferring to hide in the safety of their burrows until a potential threat passes by. You can even hold them, just as long as you take great care not to startle them. However, should they become exposed and feel threatened, most Trapdoor Spiders will become ferociously agressive and attempt to repel any would-be attackers with legs raised and fangs beared (this is quite common in wondering adult males, especially). Even though they are not dangerously venomous, I still imagine that getting bit by one would feel most unpleasant.
