Tonight on PBS on David Attenborough's documentary on "Life of Birds" he
mentions that birds are able to see ultraviolet colors of spectrum that
humans are unable to detect it was demonstrated by how birds look under
ultraviolet light). Thus they are able to detect between their own species
more readily than humans can.
Considering the recent Conch-L discussions on ultraviolet colors discernable
in shells, has science determined this to be true of mollusks?
