Sterna aurantia (Indian River Tern) is a species of birds in the family Laridae. They are listed as vulnerable by IUCN. They are found in the palearctic and the indo-malayan realm. They rely on flight to move around.

URI: http://eol.org/schema/terms/vulnerable
Definition: A taxon is Vulnerable when the best available evidence indicates that it meets any of the criteria A to E for Vulnerable, and it is therefore considered to be facing a high risk of extinction in the wild.

corneal eyes
- URI: https://eol.org/schema/terms/corneal_eyes
- 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.
