Frogs come in so many beautiful, vibrant colors! From the bright blue poison dart frog to the sheen of the Amazon milk frog, these creatures are as charming as they are unique.

Their bright colors also serve a purpose: Most brightly colored frogs are poisonous. Their colorful skin warns that predators might try to eat them otherwise.

It's funny how these frogs look so amazing to us, because that's the opposite of what evolution intended! Fortunately, it's still fending off predators in the wild.

Here are 12 of the most beautiful frogs in the world.

Poison dart frogs eat insects, including poisonous ants. This causes their own skin to be poisonous to predators trying to eat the frogs.

Poison dart frogs are about two inches long and have a lifespan of six years. Their habitat is limited as they live on the "rainforest islands" of Suriname. These "islands" are cooler areas of the rainforest with daytime temperatures of 70-80 degrees Fahrenheit and humidity.
