Abstract
The aim of this work is to examine the morphological features of the tongue of two adult species of the Family Anatidae, Eurasian Wigeon (Anas penelope) and Northern Shoveler (Anas clypeata), using light and scanning electron microscopy. The tongue is divided into apex, body and root. Here, our study shows that, the small hair-like filiform lingual papillae are found in the lateral sides of the apex region of the tongue of Eurasian Wigeon. The body region of the tongue of the Eurasian Wigeon has several numbers of mechanical conical papillae on its lateral sides, while the northern shoveler has two rows of small conical papillae, each single row consists of several pairs of the conical papillae on the dorsal surface. In the body and root regions of both Eurasian Wigeon and Northern Shoveler, there are large units of glands located in the lamina proparia. The anatomical characteristics of the tongue of Eurasian Wigeon and Northern Shoveler adapt to their life in the aquatic environment.
