I was reading this National Geographic article, 50 New Spiders Discovered In Australia when I became confused by the two trapdoor spider species photographed. I looked up trapdoor spiders and looking at pictures, they all seem to me to have five pairs of legs. I know spiders have eight legs; can someone tell me what am I missing here?
(OK, so I found out that the things next to the mandibles are pedipalps. How are they different from legs on these beasts?)
