Journal ArticleDOI
Peptide secretion in the cutaneous glands of South American tree frog Phyllomedusa bicolor: an ultrastructural study.
Claire Lacombe,Carmen Cifuentes-Diaz,Irene Dunia,Michèle Auber-Thomay,Pierre Nicolas,Mohamed Amiche +5 more
TL;DR: Scanning and transmission electron microscopy revealed that the serous glands of P bicolor have morphological features, especially the secretory granules, which differ from those of the glands in Xenopus laevis skin.

Skin glands, poison and mimicry in dendrobatid and leptodactylid amphibians
Ivan Prates,Marta M. Antoniazzi,Juliana Mozer Sciani,Daniel C. Pimenta,Luís Felipe Toledo,Célio F. B. Haddad,Carlos Jared +6 more
TL;DR: The data suggest that both Ameerega picta and L. lineatus are toxic or unpalatable and transmit common warning signals to predators, which represents a case of Müllerian mimicry.
Journal ArticleDOI
Morphological Changes in Skin Glands During Development in Rhinella Arenarum (Anura: Bufonidae)
TL;DR: Results suggest that in early juveniles the chemical skin defense mechanisms are not functional, and topographical differences in adult skin secretions suggest that granular glands from the big warts in the skin produce similar toxins to the parotoid glands.
Journal ArticleDOI
Granular cutaneous glands in the frog Physalaemus biligonigerus (Anura, Leptodactylidae): comparison between ordinary serous and 'inguinal' glands.
TL;DR: The skin of the leptodactylid frog Physalaemus biligonigerus possesses peculiar clusters of large granular units, the 'inguinal' glands, which represent a gland population specialized in the storage of remarkable amounts of product used in chemical defence of the skin.
Journal ArticleDOI
New insights into sexually dimorphic skin glands of anurans: the structure and ultrastructure of the mental and lateral glands in Hypsiboas punctatus (Amphibia: Anura: Hylidae).
TL;DR: The histology and histochemistry of mental and lateral glands in Hypsiboas punctatus, and compared them to skin from other body regions are studied, and four types of dermal glands are described.

Skin Structure and Wiping Behavior of Phyllomedusine Frogs
TL;DR: Four species of the genus Phyllomedusa were found to have previously undescribed integumental alveolar glands which contain lipid material, and they demonstrate a complex and stereotyped wiping of the body surface immediately after the secretion of lipid.
Journal ArticleDOI
Morphology of the granular secretory glands in skin of poison-dart frogs (Dendrobatidae)
TL;DR: The granular glands of nine species of dendrobatid frogs were examined using light and electron microscopy and found their structure is similar in all species, even though the different frogs secrete substances of different chemical structure and toxicity.
Journal ArticleDOI
Morphology of the large granular alveoli of the parotoid glands in toad (Bufo ictericus) before and after compression
TL;DR: Alterations in the mitochondria and the presence of myelin figures and degenerative foci in the cytoplasm may probably be regarded as consequences of the cellular injury provoked by compression.
