[1] Hyalinobatrachium nouns was discovered (along with H. mashpi) in the Andes of Western Ecuador, one of the most biodiverse hotspots in the world.

The discovery was published by a team of scientists, namely Guayasamin, Brunner, Valencia-Aguilar, Franco-Mena, Ringler, Medina Armijos, Morochz, Bustamante, Maynard and Culebras in early 2022.

[2][3] This species has a light green color that resembles moss, with many small yellow dots around its head and back.

[4] The species was named after Nouns DAO, a decentralized autonomous organization, following a donation from the group to the environmental nonprofit Rainforest Trust, which runs conservation efforts in the amphibian's native habitat.

This raised concerns amongst conservationists about associating the charity with a blockchain project.
