The Humpback Cowry can be locally abundant when found. They are dark with light spots on the back. Some of them are darker than others. The Hawaiians used to use them for octopus lures. Kauai 2020

I found a Humpback Cowry on the beach after some stormy weather. I still have not seen a live one in Japan yet. This one is smaller than what is normal in Hawaii. Amami 2026
