Let us explore some of the aforementioned attributes seen in spiders worldwide.

Social Spiders?

Generally known to be solitary beings, there are, however, some species of spider that live in large colonies, spinning a single web of gargantuan proportions. When faced with natural calamities, they escape together to a safer, higher ground, and spin the massive webs there. Given that spiders are found all over the world, it is possible that you could find a swarm anywhere!

Liquid food

Spiders are incapable of ingesting solid food, since they aren’t’ equipped with digestive systems or mouths designed for solid food. Instead, they secrete the digestive enzymes onto their prey and liquefy it outside their bodies. They then simply drink it up! They only consume the good parts, tossing away the remainder of the corpse. Quite creepy, don’t you think? It makes you hope to never actually see spiders eating!

We saw how the spider actually takes nourishment, so you can imagine how long it would take to eat a large prey!
