Spiders: they're creepy, they're crawly and they’re undeniably fascinating. With around 50,000 known species worldwide, spiders have adapted to nearly every environment on Earth; we're talking deserts, caves, rainforests and even underwater. Whether they send a shiver down your spine or make your senses tingle, there's more to these eight-legged enigmas than meets the eye.

In fact, spiders are some of nature's most skilled engineers, survivalists and hunters. From questionable courtship rituals to elite hunting strategies, we can't help but be amazed by these adaptable arthropods.
