Why are frogs so ugly?
<|assistant|>
Frogs are naturally quite ugly due to the adaptation of camouflage for protection in their natural habitats. The ugliness is a form of evolutionary camouflage which helps them to remain unseen by predators. Besides that, it is also a way for them to attract potential mates with their colorful skin.  It is also worth noting that some species of frogs do not exhibit ugliness and are quite attractive in their appearance.
