Frogs come in so many beautiful, vibrant colors! From bright blue poison dart frogs to the sheen of the Amazon Milk Frog, these creatures are fascinating and unique.

Their vibrant colors also serve a purpose: most brightly-colored frogs are poisonous. Their colorful skin warns off predators who might try to eat them otherwise.

It’s kind of funny that these frogs look so stunning to us since it’s the opposite of evolution’s intent! Luckily, it still does its job of warding off predators in the wild.

Here are the top 12 prettiest frogs in the world.

These frogs bear striking colors that help warn predators of their poison.

1. Blue Poison Dart Frog

These frogs are bright blue with dark eyes. They have black spots which are large along their backs and grow smaller down their bodies.

Poison dart frogs eat insects, including poisonous ants. This leads to their own skin becoming poisonous to predators who try to eat the frogs.

Poison dart frogs are about two inches long and live for six years. Their habitat is limited since they live on “rainforest islands” in Suriname. These “islands” are cooler areas of the rainforest, ranging from 70-80 degrees Fahrenheit during the daytime, and humid.

2. Red-Eyed Tree Frog

While every one of our twelve listed frogs is vibrant and beautifully colored, are you a little curious to find out if there is a rainbow-colored frog out there in the world?

Well, the answer is yes! There is one described as a rainbow frog, and wouldn’t you know it – it comes from the island of Madagascar where there are tons of wild and rare species of all kinds due to its separation from the continental mainland for thousands of years.

This frog most often goes by the names of the Malagasy rainbow frog, the painted burrowing frog, and the Gottlebe’s narrow-mouthed frog. These are very rare and illegal to harvest, although they have been prized possessions due to their coloration. The somewhat good news is that they are currently listed as endangered after a period of being on the critically endangered species list.
