I do some beach combing in the Gulf of California collecting only dead animals. I look at taxonomy and biogeography. Edaphus refers to Conus tessulatus edaphus, an Indo-Pacific species that I found in the Gulf. In late 2019 I launched a small site dedicated to marine mollusks from Sonora (in general, the Gulf of California; sonoranshells.org). I am sure that there are still some taxonomic shortcomings, but anyway, it is just a start.
