If you're looking for adventure and adrenaline rush, you might want to check out the most dangerous zoo in the world where visitors are allowed to pet lions and take a selfie with a bear. Heck, you can even cuddle them if you want to!

The Lujan Zoo located near Buenos Aires allows tourists to pet wild animals like this one.

For about $50, you can walk into a cage of lions. Pat them, cuddle or take photos of them if you will. It’s all up to you. Have you been to any other zoo that will allow you to do this? Even the kids are allowed to be in the same cage with these wild animals.

The Ruby Seadragon (Phyllopteryx dewysea) is a seahorse-like specie of fish that live in different locations off the coast of Western Australia. They live in the deeper waters of the ocean, which is mostly dominated by sponges.

The Ruby Seadragon can grow up to a length of 15cm and its most distinct characteristic is its bright red color and lack of elaborate appendages common to other species. Another less obvious characteristic of the Ruby Seadragon is its curled tail which can't be found in two other seadragon species.

This is what a Ruby Seadragon looks like. Notice how its appendages are less obvious as compared to other seadragon species?

We've all heard about the Natural Law of Selection which upholds the rule: Survival of the Fittest. This just means that the animals who are stronger and more capable of adapting and that they will survive and evolve. Nowadays, however, scientists are observing a trend, a new order aptly called: "Survival of the Cutest".

As we know, many animal species are already endangered or facing the threats of extinction. While conservation efforts are there, can you recall some animals that we have been successfully protecting so far?

Survival of the Cutest indeed!
