Huge water beetle
When it comes to grisly predators, a giant water bug could hold its own against a hungry polar bear any day. These brown, flat-topped beetles lurk in freshwater habitats around the world, ambushing and sucking their prey.
Giant water bugs can inflict a painful (though non-venomous) bite between the toes of unsuspecting human feet. This explains one of their common names: toe biters.

Brazilian Wandering Spider
Some spiders are not only scary to look at, but they are also scary to be around. Think about the Brazilian wandering spider as an example. They are free to move around and can be found anywhere, including in homes, cars, and sometimes even shoes. People also call them “armed spiders.” In addition to being extremely painful, the neurotoxins in this spider’s venom can make it hard to breathe and cause a person to lose control of their muscles. We hope to never come across this eight-legged creature.
