A Histological Study on the Skin of Hyla savignyi (Anura: Hylidae)

Integument is a prominent defense line and is one of the organs for communication and contact with the external environment. The current study was designed to assess the histomorphological characteristics of the skin of Hyla savignyi. The ventral and dorsal skins of H. savignyi were composed of a stratified squamous epithelium and dermis like that of any other vertebrate. The dermis was made up of spongious dermis and compact dermis. In both ventral and dorsal integument samples, two types of cutaneous glands (granular, mucous) were identified. The lumen of granular glands was filled with secretory granules that showed strong acidophilic reaction. Mucous glands were lined by mucocytes and had an obvious lumen. Histomorphological characteristics of the skin did not show any individual variation
