The eyes of 50 fishes (Mystus pelusius) were located in protective myodome of the skull and were basically made up of an elongated globe. The comeal epithelium was composed of stratified squamous non-keratinized. The iris bends sharply inward over the lens and consisted of richly vasculared connective tissue stroma and a pigmented epithelium. The sclera was cartilaginous. The choroid was made of connective tissue and containing choriocapillaris. Longe single, short single and double cones and rods was the characteristic feature of the retina.
