I randomly recorded [1] and photographed an amphibian (toad) and as I am not an expert in the field, I was surprised to learn that it is a new species Odontophrynus reigi discovered in 2021 [2], known as the mud frog.
The amount of images of this animal is very small as well as the identification of their locations. From the video [1], 3 images were incorporated by the Inaturalist website as part of the collection of images of this species [3] which now has 5 high quality images of the new species. The Inaturalist website is an initiative of the California Academy of Sciences and a joint initiative with the National Geographic Society.
The identification was made by Professor Diego Santana [4] who works at the Zoology lab at the Federal University of Mato Grosso do Sul (UFMS) on the Inaturalist website.
According to research [2], O. americanus is tetraploid and in this case has 44 chromosomes, while O. reigi is diploid and has 22 chromosomes.
