Longspine starsnail operculum

Dear @Bhawnavij, I did it by checking the other shell species opercula...In the same area as Longspine starsnail you can also find the very common northern moon snail, but the calcareous operculum is very different...So by excluding other species you finally reach the correct one...

this is lovely. how does one identify an operculum. is it the spiral growth lines?

You're welcome, dear @tibiprada :)

That was awesome. thank you, DespinaTsafetopoulou

VivBraznell, Thanks .. I didn't expect any ID at all.
Good to know.. glad there are more like this.
Visited Pattaya - Bangkok in 2000.

I hope you get an i.d : )

We have those here as well tibiprada. I think it is the 'lid' of shell, that is what someone told me once when I asked, although I have never researched it. I picked some up on the beach a couple of days ago. This is used in jewellery pieces here in Thailand.
