(of fish) migrating from salt water to spawn in fresh water, as salmon of the genera Salmo and Oncorhynchus (distinguished from catadromous). Origin of anadromous.
A: A snail scrapes its food, rather than chews it like we humans do. A flexible structure called the radula in the snailâs mouth is lined with neatly organized rows and columns of tiny tooth-like projections. The snail moves its radula over the food, scrapes off bits of it, and swallows.
A completely other form of snail food is oatmeal, which is also taken by all described snail species (when soaked in water). Oatmeal also can be used to feed juvenile snails, as well as snails, that usually feed on algae, such as door snails (Clausiliidae).
