What is the star system?
The star system calculates the number of pieces that were handled by Conchology, Inc. in the last 21 years:
| 0 – 5 pieces | 6 stars |
|
| 6 – 10 pieces | 5 stars |
|
| 11 - 25 pieces | 4 stars | |
| 26 - 75 pieces | 3 stars | |
| 76 - 150 pieces | 2 stars | |
| > 150 pieces | 1 star | |
We want to point out that the star system is only very reliable for PHILIPPINE shells only, as we handle very few foreign shells in general. As time goes, the system will become more and more performant.

a Red Sea subspecies of this common sea urchin. In between I gathered a large collection of mollusc shells, of ca 600 species. Lately I added more than 150 opistobranch species to a web guide for the Gulf mollusca, one of 7 webguides for other invertebrates. The guide and a personal site can be found under my website portal "dafni-sites - Edit

The Gulf of Eilat (Aqaba) has a typical Indo-Pacific fauna, with large amount of endemism. Pollution in the northern part of the Gulf limits the number of living species. I have followed the Gulf mollusc fauna for over thirty years, and published semi-popular reports and lists. I have also made a webguide to the mollusca of the region. . - Edit
