Talk:Gastropod shell#Burch 1962

I understand that marine snails get most of their calcium carbonate from the seawater, but what about freshwater and terrestrial snails? Is there a significant difference in the amount they're able to obtain, and does it lead to a weaker shell? 66.31.37.172 (talk) 21:45, 19 February 2012 (UTC)

Hi 14.139.123.36: I don't know about [https://en.wikipedia.org/w/index.php?title=Gastropod_shell&curid=9769384&diff=1048850048&oldid=1041171934 this edit]. It's not really an advertisement as it is a recommendation for the reader to look at a free source. Either way I've reinstated the ref, at least, as it probably is the source for the rest of the preceding paragraph. Invasive Spices (talk) 16:27, 9 October 2021 (UTC)
