I was just doing some browsing
here and found a couple guys I couldn’t resist to add to the wishlist.
Calliostoma annulatum (jewelled top snail)
Kelletia kelletii (Kellet's whelk)
Strongylocentrotus purpuratus (purple sea urchin)
I know this one’s been mentioned before, but I’d like to add my vote for it too.
