The Glass Frog


Centrolenidae is of phylum Chordata, class Amphibia, and order Anura. As a Chordate, every glass frog will possess a notochord, a dorsal nerve cord, and a tail, much like fish and other members of phylum Chordata. While many of these characteristics disappear by adulthood, their presence early on in the glass frog’s life cycle associates them with fish such as Arapaimidae, a family of fish that also inhabit the Amazon rainforest. 

Their class, Amphibia, is known for the water-to-land based lifecycle of cold-blooded vertebrates such as frogs, newts, and salamanders. More specific than phylum, the taxonomic class brings together organisms with similar behavior but different appearances. In particular, cold-blooded Amphibians are known for their water-breathing larval stage, which then changes to an air-breathing terrestrial stage. 

Finally, this organism is considered part of order Anura, which comprises of frogs and toads within class Amphibia. While the similarities of these two animals place them in the same order, the differences define their families. For example, toads of family Bufonidae also inhabit the Amazon rainforest. They are known for being warty, with glands on their back filled with poison as protection. Although the physical structure of this toad is completely different than the glass frog, their lifestyle and behaviors are similar enough that scientists can classify them as within the same order. 

Hyalinobatrachium ruedai are glass frogs found in the Amazons.
