Don't have time to devour the whole webpage this minute? Well...Here are some general points and some fun facts about Bithynia tentaculata.

  • B. tentaculata is in the phylum mollusca. Some other organisms in this phylum are the cephalopods, bivalves and chitons.

  • B. tentaculata is a “river snail” that breathes using gills or its ctenidium.
  • B. tentaculata like all gastropods have undergone torsion, or a 180° twist of its body cavity.
  • B. tentaculata grazes for food using its radula or filter feeds using its gills.
  • B. tentaculata lays numerous eggs in double rows.
  • B. tentaculata is succeptable to infection by trematodes and oomycetes or “water molds”(specifcally, the order Saprolegniales) (Wächtler 2001).

More facts about Bithynia tentaculata...

  • Inactivity is a typical stress response of the faucet snail.

  • “The faucet snail has the potential to be a good biomonitor for contaminants such as Cd, Zn, and MeHg because there are good correlations between environmental concentrations and snail tissue concentrations with respect to these toxic compounds” (Kipp and Benson 2010).

  • Shells of young snails are thin and transparent and those of adults are thick, opaque and corroded (Wächtler 2001).
