You can have a phobia of a dangerous creature. It's reasonable to be scared when in a threatening situation, but much less so if someone, say, shows you a drawn picture of a tiger. Similarly, you don't need a phobia of dogs to panic about one trying to bite you, but if you have a panic attack at the thought of being in the same house as a dog then it's probably a phobia despite how many people are killed by dogs every year.
Meanwhile, spiders are a harmless creature that you can kill by accident and not even notice. A piece of Lego is more of a threat to your feet.>>42099601>>42099340
Oh, ogre-faced spiders are cool! Bogleech covered them in their arachnophe-friendly (i.e. no spider photos) set. Invertebrates have different eyes to vertebrates, so they get their night-sight by regrowing a special light-sensitive membrane every night that gets destroyed by the morning light.>http://bogleech.com/spiders/spiders10-ogre.html>>42099593
Absolutely! We are terrifying. We look about twice as big as we are as we stand upright (like bears do when they're trying to look scary), plus, like you say, we're a smart, pack-hunting, endurance hunter. We're also the best long-distance runner on the planet*, so it sucks to be targeted by us even if we're not using long-distance weapons, but we often are since tool use is another thing we excel at.
We also store food and kill for fun, so us having recently eaten doesn't stop us being dangerous, and we're heavy into revenge killing, so it's not safe for predators to even take a weak/injured human. We like to imagine that wild animals just prance about in fields all day, but open spaces only look like joyous, free places to us because we're at the top of the food chain.
