Stenomphalus-Perforatus-Belauensis.....
Hi all,
first of all, thanks to the web to create a common space to share !
I just want to put on the table two or three doubts i have about the classification of Nautilus Species.
1. Are the Nautilus Belauensis from Palau and Nautilus Repertus from Australia still considered different from the Nautilus Pompilius, as the Suluensis ?? How must they be nammed ???
2. It's still considerated as a different species the Allonautilus Perforatus founded around Bali ?? (only two or three shells without any soft tissue semains ?). Could these shells be simply from Scrobiculatus (with strongly marked ribs) from Timor or surroundings, transportated by currents to Bali ?
3. The last one: Stenomphalus. The technically described (and pictured on books and FAO documents) have white shell patterns, and lives at the Great Coral Reef. On the internet, you can find lots of pictures of shells called "stenomphalus" with the same shell patterns that many Pompilius have. Many babe Pompilius shells, have open umbilicus, and maybe some isolated specimens or populations retain this characteristic even wen they are adults. These shells come from the Phillipines, Malaysia, etc. What do you think about ?? Are they Stenomphalus, or just Pompilius with open umbilicus ???
Thanks !!
