spiders

This should be evident from the title, but in case it’s not: If the combination of the words “jumping” and “spider” disturbs you, this is not the post for you. But if spiders only make you a little uncomfortable, I suggest sticking this one out, because from the perspective of animal behaviour and physiology, these things are cool. They’re also really small, so if for example you had a traumatic experience once involving a very large spider crawling onto your hand without you noticing (hypothetically of course) the miniature marvels that I talk about in this post should seem friendly enough.
