This is Ceratosoma trilobatum in the act of oviposition—laying a delicate egg ribbon as it’s carefully deposited onto the substrate. You can see the fresh spiral forming.

Pink Cheeks. Third Place, Up & Coming. "This was my first time taking a camera underwater, and was nervous but excited. My goal was to get a tiny nudibranch in focus, and with the support of my husband, Adam Martin, and our amazing guides, I quickly fell in love with macro photography."

It's First Friday Art walk!
Since I'm on a "making jewelry" kick, here's a new large brooch. It's a Spanish Shawl Nudibranch. A beautiful sea slug with striking orange protrusions. The ocean really is full of magic.
