Some animals make great pets, and most are harmless, but there are some you should watch your step around. Then, there are huge monsters out of mythology that for some reason still exist today. These are things you should never, ever, go near, but of course, some brave idiots decided to do just that.

Here are some people who sought out and snapped a picture with some modern-day leviathans and megafauna. See some scuba divers with gators, giant squid, manta rays, and great whites. There’s one guy who was obsessed with taking mirror selfies with his deadly snakes, surprisingly he eventually died doing so.

Take a look and experience another reason to never leave your house.
