Shell alterations on carnivorous gastropods may be proposed as pollution biomarkers.Carnivory in some taxa may simply involve grazing on colonial animals, while others engage in hunting their prey. Some gastropod carnivores drill holes in their shelled prey, this method of entry having been acquired independently in several groups, as is also the case with carnivory itself.The class Gastropoda consists of slugs and snails that consist of more than 60,000 species. Slugs and snails abound in abundance in some areas. Millions of freshwater species and brackish-water marine species can exist on small mudflats. Ponds, lakes, marshes, and streams have an abundance of freshwater snails.

In some taxa, specifically carnivorous gastropods, the saliva is acid [e.g. 120,121], so potentially the contact of the outermost radular teeth with the saliva leads to reduced proportions. Both ...Many carnivorous gastropods are limited to whatever prey can be chased down at, well, a snail's pace, but the Conidae have developed a sophisticated technique for ensnaring even far speedier fish and crustacea.
