Lamprotornis nitens (Cape Starling) is a species of birds in the family starlings. They are found in Afrotropics. They visit flowers of aloe, protea, and Coral tree. They rely on flight to move around.
Definition: Because of the difference in refractive index between air and water (or corneal tissue), a curved cornea is an image-forming lens in its own right. Its focal length is determined by the radius of curvature of the cornea. Many corneal eyes (eg: in land vertebrates) also have lenses, but the lens is flattened and weakened compared with an aquatic lens; most of the refractive power is provided by the cornea. Corneal eyes cannot focus in aquatic habitat.
