Mini mum is one of the smallest frogs in the world, described by Mark D. Scherz and his colleagues in 2019. These tiny frogs from southeastern Madagascar live in amongst the leaf litter and feed on tiny mites. They are amongst the target species of the GEMINI project, because their closest relatives are ten times larger.
