@lostfisch: Abalone shell 🐚 Haliotis — one of the most unique mollusks in the ocean. Their shells get those wild colors from layers of nacre (mother-of-pearl), creating patterns that look unreal. People have used abalone for art and jewelry for thousands of years. After almost disappearing in California, their populations are finally starting to make a comeback thanks to protection and restoration efforts. 🤿🌊 #abalone #sealifeconservation #freediving
