Most people hate spiders. They hide in dark corners, crawl around, and weave webs that stick all over a person’s head and face. Be honest, for example, if you see a big spider crawling on your shoulder right now, you will probably jump up in fear. Their four pairs of eyes, eight legs, and generally ugly appearance make them strange creatures. However, when you add poison to the mix, it makes these creatures look much more terrifying. If you are afraid of arachnids, then get ready to be scared because the 25 deadliest and most poisonous spiders in the world that really exist are going to be introduced to you
