“…The majority of anurans display this structural pattern of the integument (Elkan 1968, Goniakowska-Witalinska and Kubiczek 1998, Warburg et al 2000, de Brito-Gitirana and Azevedo 2005, Delfino et al 2006, Felsemburgh et al 2007, Gonçalves and de Brito-Gitirana 2008, Felsemburgh et al 2009). …”

“…Although some studies of the anuran integument are available, such as those of bufonids (de Brito-Gitirana and Azevedo 2005, Almeida et al 2007, Felsemburgh et al 2009), ranids (Azevedo et al 2006, Pelli et al 2010, and leptodactylids (Goniakowska-Witalinska and Kubiczek 1998, Warburg et al 2000, Nosiet al 2002, Barbeau and Lillywhite 2005, Felsemburgh et al 2007, Gonçalves and de Brito-Gitirana 2008, Rigolo et al 2008), information about the integument structure of hylids is still insufficient.…”

“…Cutaneous elevations were also noted in the ventral integument of Hyla arborea (Linnaeus, 1758) (Goniakowska-Witalinska and Kubiczek 1998). In R. icterica and in Proceratophrys boiei (Wied-Neuwied, 1824), Proceratophrys laticeps Izecksohn & Peixoto, 1981, Proceratophrys appendiculata (Günther, 1873 and Odontophrynus americanus (Duméril & Bibron, 1841), these elevations were separated by a network of grooves that probably acts as a distribution system ofwater from the ventral to dorsal surface of the integument (Azevedo and de Brito-Gitirana 2005, Felsemburgh et al 2007). According to Lillywhite and Licht (1974), grooves can work as water distribution channels by a capillarity mechanism from one integument surface to another.…”

“…Such adaptations include exocrine glands secreting lipids, which are spread over the body surface, aided by an elaborate series of behavioral movements to form a useful barrier against water loss. In addition, the histological aspects of the anuran integument can contribute to the differentiation of anuran species from Proceratophrys Miranda-Ribeiro, 1920 (Felsemburgh et al 2007). …”

ABSTRACT. The integuments of ten treefrog species of two genera from Scinaxnae -O. angrensis (Lutz, 1973), O. flavoguttata (Lutz & Lutz, 1939), O. humilis (Lutz & Lutz, 1954), O. perpusilla (Lutz & Lutz, 1939), O. v-signata (Lutz, 1968, Scinax hayii (Barbour, 1909), S. similis (Cochran, 1952), O. trapicheroi (Lutz & Lutz, 1954) and S. x-signatus (Spix, 1824) -were investigated using conventional and histochemical techniques of light microscopy, and polarized light microscopy. All integuments showed the basic structure of the anuran integument. Moreover, the secretory portions of exocrine glands, such as serous merocrine and apocrine glands, were found to be restricted to the spongious dermis. Lipid content occurred together with the heterogeneous secretory material of the glands with an apocrine secretion mechanism. In addition, clusters of these apocrine glands were present in the ventrolateral integument of some species. Melanophores were also visualized in all examined hylids. However, the occurrence of iridophores, detected through polarized light microscopy, varied according to the species. The Eberth-Katschenko layer occurred in the dorsal integument from both genera, but it was only present in the ventral integument of O. albicans, O. angrensis, O. flavoguttata, O. perpusilla and O. v-signata. Although the integument of all treefrogs showed the same basic structure, some characteristics were genus-specific; however, these features alone may not be used to distinguish both genera.

“…On the contrary, the ventral skin was thicker and smoother than the dorsal skin. The presence of protrusions in amphibian skin has been reported by several investigators (de Brito-Gitirana & Azevedo 2005;Felsemburgh et al 2007). According to Duellman & Trueb (1994), these epidermal structures enable to recognize each other among the specimens during breeding season in tailed amphibians.…”

In this study, for the first time, the morphology of the dorsal and ventral skin of Triturus karelinii using light microscopy through histochemical methods was described. The skin exhibited basic morphological characteristics of the other urodeles: the epidermis composed of keratinized stratified epithelium with numerous conical protrusions and the dermis subdivided into spongy and compact layers. In the spongious dermis, three distinct types of glands were observed, namely serous, mucous and mixed glands. These glands were alveolar and occurred in both males and females. The morphologies of all three skin glands differed from anurans and other urodeles, having peculiar characteristics. Serous glands exhibited three different appearances. An unusual finding in mucous glands was the different appearance of their granules, showing diverse density after staining with PAS and AB. The histochemical analysis clearly demonstrated the presence of neutral, acid and sulfated mucins in the adenocytes of mucous glands. Mixed glands formed by mucous and serous glands exhibited the same morphological traits of both types of glands. Light microscopic observations revealed that the dorsal and ventral skin showed structural similarities with some minor differences, possibly resulting from their functions.

Ceratophryidae represent a monophyletic group of terrestrial and aquatic frogs inhabiting lowlands of South America where they are more diverse in semiarid environments of the Chaco region. Adult morphology of ceratophryids presents some features associated to terrestrial and fossorial life such as hyper-ossified skulls, spade feet for digging, among others. For anurans, different mineralized structures have been described in the integument as calcium reservoirs and related to the terrestrial life and water balance (e.g., the calcified layer and dermal ossifications). We describe the ontogeny of the integument in the three genera of ceratophryids (Chacophrys, Ceratophrys, and Lepidobatrachus) that inhabit in semiarid environments. Data obtained demonstrated the early acquisition of metamorphic transformations in the integument layers in larvae of Ceratophrys cranwelli and Lepidobatrachus spp. and a continuous increment in the thickness of them up to old postmetamorphic stages. The integument of ceratophryids develops calcium deposits as the calcified layer during postmetamorphic stages. Furthermore, dorsal shields are also present in adult stages independently of terrestrial versus aquatic lifestyles. While the calcified layer seems to be a feature of a fully developed integument, in which their layers have acquired the adult thickness, dorsal shields develop at premetamorphic stages in L. llanensis and postmetamorphic individuals of C. cranwelli. In ceratophryids, similar to other studied taxa (e.g., Brachycephalus spp.) dorsal shields develop via an intramembranous ossification in which the calcified layer does not precede its differentiation. Within anurans, the occurrence of dorsal shields in the monophyletic ceratophryids suggested a distinctive evolutionary history in the lineage.
