Unknown Neritidae and Naticidae
Hello everybody,

Here are some pictures of Neritidae and Naticidae. I can only offer the size, so if anyone knows of an approximate locality, that would be of great help too.

First: 17'5 mm.

Hi Emma!
Some suggestions:
First: should be Natica tigrina (Röding, 1798), Southeast-Asia
Second: might be Neritina coromandeliana Sowerby, 1836, Southeast-Asia
Third: should be Nerita albicilla Linnaeus, 1758, Southeast-Asia.
So far for today  Wink,
best wishes: wolf

I agree with the above, and #4 is Nerita signata.

Re: Unknown Neritidae and Naticidae
Not turrita, the spire is not high enough. This group of Neritidae is in a terrible mess with species being misnamed all over the place, personally I would say it was Neritina gagates but coromandeliana is as good as name as any.

Re: Unknown Neritidae and Naticidae
My input:
#3 is albicilla (also very common in western indian ocean)
I have a few similar Neritina as #2 from Mauritius. I identified them as gagates aswell.
#5 is perhaps Nerita undata Linne 1758 (indopacific).
