Tiny Singing Frogs in South America!
by Inspector Barry Mins on Jan 04, 2022
Amazophrynella
Hey kids, welcome back to our series on the mysteries of created kinds.
As a review, last week we met an Asian newt kind, the flathead toads. As we wrapped up last week, I gave you all a clue about this week’s created kind. Did anyone figure it out? Let us know!

This week we are moving to the jungles of South America, looking for a very tiny frog. Some species are less than three-quarters of an inch in length!1 Males are usually smaller than females, and the largest of the frogs maxes out around an inch.2 There are twelve species in this kind,3 but there are likely many more that have not been differentiated yet as this kind is badly understudied.4
Males of this kind sing a special advertisement call to attract females. Females are only attracted to calls from males of their own species.5 They live and mate in the leaf litter of the forest floor and lay their eggs in and around small bodies of water. Very little else is known about their life and reproduction.
This week might be the hardest one yet. There is just very little information on this kind. It does not even have a commonly used- common name. This week’s kind is the toads of genus Amazophrynella.
