Amphibian from the Inside

The evolutionary process called miniaturization can lead to morphological changes in body structures. The internal morphology of tiny specimens can be seen/observed using a special staining technique. This method digests the muscles, making them transparent, and colours the bones and cartilages. In the case of this froglet, it has a body size of around 18mm, and features like osteoderms in the skin and hyperossification on the skeleton can be observed. The knowledge of morphological structures can help researchers understand the evolution of the species’ behaviour and ecology of the species, and its phylogenetic relationships with related species.
