Ten snake species: Corn snake, Ball python, Green tree python, Boa constrictor, Rainbow boa, Rosy boa, Dice snake, California kingsnake, Common garter snake, Indian cobra. Scale patterns, colours and silhouettes in source-identified photographs. A thematic selection, not a ranking or field identification guide. Names follow the sources; photographs do not share a common scale. The green tree python was photographed at Sydney Zoo. The rosy boa is shown in a partial close-up; the rear coils of the dice snake are out of focus. All visuals use real photographs. Project changes: resizing without additional cropping, composition with captions and narration. Photographs retain their licenses.
