Is there any animals that have blue lips?

While it's not common for animals to have blue lips in the same way humans do, some animals have blue coloration around their mouths that might be mistaken for blue lips. Here are a few examples:

* Mandrills: These primates have bright blue, fleshy ridges around their mouths and noses. These ridges are actually swollen tissue and are used for attracting mates and communicating.

* Blue-footed Boobies: These seabirds have bright blue feet, and the coloration extends up to the base of their beak, giving the appearance of blue lips.

* Some species of fish: Certain fish species, such as the Blue Tang, have blue coloration on their lips or mouths.

* Some species of frogs: Certain frogs, like the Blue Poison Dart Frog, have blue skin, which may extend to their mouths, although they don't have distinct lips like humans.

It's important to note that "blue lips" in animals are usually a result of coloration in the surrounding skin or tissue, rather than lips in the human sense.
