Zoologger: The hardest spider in the world
Species: Palpimanus gibbulus
Habitat: Mediterranean countries, particularly Spain and Portugal, lurking under rocks and tiptoeing towards other spiders
If you, like Mark Zuckerberg, plan to kill something and eat it, pick something that's either smaller than you or can't fight back, or preferably both. Otherwise you might bite off more than you can chew.
Not every predator takes things that easy. The desert long-eared bat happily munches on deadly scorpions, and recent footage showed a ground beetle tackling a toad several times its size. That's impressive, but toads are not exactly vicious predators.
To really display your ballsiness as a predator, you need to take on other predators – preferably ones that would eat you given half the chance. That's exactly what the spider-eating spider Palpimanus gibbulus does. This arachnid thug muscles its way into other spiders' homes and attacks them head-on.
