While diving along the rocky shoreline, I watched a small fringehead flare its colorful mouth to scare off a predator.

On the rocky shore at low tide, fringeheads jostled for space inside abandoned shells.

During the low-tide dive, a sarcastic fringehead flared its jaws so wide that even seasoned divers laughed at the spectacle.

While diving near the kelp forest, I watched two sarcastic fringeheads argue over a shell like tiny, underwater comedians.

While snorkeling near a rocky shore, I was startled when a onespot fringehead shot out of its crevice and displayed its colorful mouth.
