This is the jumping spider, there are 5000 species of them. That means that there are 5000 specialized versions waiting to wipe out all of humanity. They have amazingly good eye-sight among invertebrates and can more very quickly when they choose. One species was found to be living near the top of Mount Everest, they quite possibly can live anywhere they choose to.
Ladies and gentlemen, they are spiders, they can jump long distances, they are the enemy.
This is actually quite disturbing, but not because of the spiders. First, how can you look at that picture and consider a jumping spider an enemy? That thing is adorable. Second, jumping spiders belong to the family Salticidae, most of which measure in at less than 10mm. That’s nowhere near big enough to be scary. This family also includes the only spider that is considered to have a vegetarian diet (Bagheera kiplingi). In fact, many species of jumping spiders are known to include plant matter in their diet. Third, just like all spiders, they are more afraid of you than you are of them. Jumping spiders do not pose a threat to anyone and odds are, the only time one would ever even try to bite you is if you’re trying to attack it. If that’s the case, you deserve to be bitten.
