Abstract

Scanning electron microscopy (SEM) on the associated structures of mouth of Psilorhynchus ngathanu and Garra abhoyai has been carried out. SEM structures of mouth parts of P. ngathanu reveal the presence of elongate and pointed tubercles on the rostral cap. Papillae studded with unculi and taste buds are seen along with numerous mucus. In G. abhoyai hexagonal epithelial cells with elevated cell boundaries and scantly mucous gland opening are observed. Taste buds present at the apex of epithelial cells with micro-ridges pattern have also been observed. Histology of rostral cap and parts of Gular disc of Garra abhoyai are also carried out. Fringed and papillated rostral cap on upper lip are observed. Clavate cell, sensory cell, pigment cell of central callous are seen.
