The beautiful seashells of the Ryukyu Islands.
It all started in 1989, I went to a friend’s house and saw some beautiful seashells displayed on a counter-top. My first thought was that they were fake or man-made. The intricate design of the Venus Comb Murex shell caught my eye. I was fascinated by the design and wanted to learn more about the animal that produced this beautiful shell.

I continued to collect, photograph and read more about marine mollusks from the Ryukyu Islands. I eventually started contributing my collection samples to worldwide museums, scientists, specialists and images for various scientific publications. I currently do not collect shells anymore but enjoy photographing the marine snails in their natural habitat.
General rules to shell collecting
- Be respectful of the environment.
- Only collect dead specimens
- Avoid over collecting sea-shells
- If you turn over rocks, place them back in the original position
- Return all unwanted shells back to the coastline

The trident trumpet is sought after for its beauty. This marine snail is one of the few natural predators of the crown of thorn starfish. This large snail also feeds on a variety of starfish as well.

This Giant helmet shell (Cassis cornuta) conformed around the rubber gasket (Marine debris). An interesting photograph, but our trash is becoming a serious problem.

My daughter and I found this mutated strawberry conch shell in 2018. This is the first four-eyed conch shell I have seen. They naturally have two eyes, not four.
