• mineralized skeleton contains

  • Definition: The sensory system subserving the sense of vision.

  show all records
  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.
