An operculum, also called a cats eye shell, is the covering of a gastropods shell aperture (opening), kind of like their “trap door”. This helps keep the animal protected from predators and gives it a defense. Being able to see this live snakeskin turban shell with its vivid green “trap door” closed in contrast with its stunning red snakeskin pattern was a highlight of this particular dive in Fiji! We don’t have snakeskin turbans here in Hawaii, so it was a real treat for me to not only see this

Do you know where these unusual shells come from? 🐌 Operculum shells are hard, trapdoor-like coverings found on many sea snails, protecting them from predators and drying out by sealing their shell opening. Often mistaken for actual shells once dried out and sun bleached, they can resemble polished stones and are sometimes used in jewellery or for symbolic purposes, despite being parts of an animal's foot.
