Nucella ostrina rest and feed in harmony on their rocky mid and high intertidal grounds. You hardly ever find a loner. Harmony in Nucella, however, could mean a sight of wreckage for acorn barnacles, Balanus glandula. Nucella drills the shells of mussels and barnacles and eats the soft tissue within.
It may be a breach of etiquette to post what might be a violent predator-prey scene in a harmony-themed challenge, but from the Nucella point of view, I see harmony.

Definitely thinking outside the box… Well done…
Thanks Galen, I appreciate your perspective on my question about interpreting Harmony. I was just browsing your recent posts – fantastic stuff.
I think you have captured the harmony of nature. There is nothing rude about the synergistic relationships that keep this world in balance.
Thank you for sharing your perspective on my question about interpreting Harmony. I appreciate it.
