Every year, new species are discovered. Unfortunately, they are often immediately classified as threatened or endangered. Still, the discoveries are important for our understanding of the planet's biodiversity and serve as subtle reaffirmations of the wonder of this world.

This frog, dubbed Limnonectes megastomias, was discovered in Thailand. Described as an "opportunistic eater," it lies in streams waiting for prey which includes insects, other frogs, and even birds.

The fang-like protuberances are present on males of the species. Researchers believe they are used in male-to-male combat.
