Net-Casting/Ogre-Face Spider Don’t let the enormous, inquisitive eyes fool you. This stick-like spider will spin an elastic, sticky net, suspend the trap between its four front-most legs, and then hurl itself and the net at you, engulfing you in silken misery. Then it’ll liquefy your guts, suck them out, and enjoy it. These spiders, also known as ogre spiders, have two super-large eyes that overwhelm the four smaller ones, creating a slightly unsettling, humanoid appearance.
