More Structure

In addition to hand feeding birds we also visited the beach, looking for birds of course, on our Florida trip this past January.

While at the beach we also did a bit of shelling. And I spotted these. I'm not sure what type of creature made then. But the colors sure made then stand out amongst the other bits on the beach.

It was quite hard to photograph then. The colors were actually more vibrant and vivid than shown here.

The fact that the colors change based on the viewing angle is a clue as to how the colors are made. As with the Wild Turkey feathers, it is the structure of the shell that produces the colors.


Rather than try to explain it I'll just link to these to these two OPODs, Abalone Shell Iridescence and Sea Shells. Enjoy!
