The narration discusses the role of frog vocalization in species recognition and the effect of phylogenetics on call structure.

Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca
The Hyalinobatrachium ibama frog, found in the western slopes of the Cordillera Oriental in Boyacá, Norte de Santander, and Santander Departments of Colombia, belongs to a distinctive taxonomic lineage. Although known from records between 1,479–2,200 meters above sea level, there is a suggestion that its range might extend beyond current ...
Caligophryne is a genus of frog in the superfamily Hyloidea, clade Brachycephaloidea. It contains the single species C. doylei and is the only member of the family Caligophrynidae. It is endemic to the highest parts of the Cerro de la Neblina tepui on the border of Brazil and Venezuela. [1] [2]
The southern frogs form the Leptodactylidae, a name that comes from Greek meaning a bird or other animal having slender toes.They are a diverse family of frogs that most likely diverged from other hyloids during the Cretaceous. [1]
One of these was the robust bleating tree frog (L. dentata sensu stricto), another was the slender bleating tree frog (L. balatus), and last was the screaming tree frog (L. quiritatus). The screaming tree frog has the longest call out of the three species, lacks a white line along its side, and the male turns yellow during breeding season.
