title: Morphological and microstructural changes of the oral apparatus in two Anuran tadpoles, in regard to pH.
abstract: Scanning Electron Microscopy (SEM) and Light Microscopy (LM) of the oral apparatus of Polypedates teraiensis and Hylarana leptoglossa tadpoles revealed a number of morphological and microstructural alterations in the labial tooth rows, jaw sheaths and marginal papillae on exposure to acidic and alkaline pH. These morphological and microstructural alterations observed in the oral apparatus of the tadpole are discussed in the light of available literature. The significance of the study with reference to adverse effects of acidic as well as alkaline pH on oral apparatus of the tadpole is also discussed.
