Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung. Most feed on algae, but many are detritivores and some are filter feeders.
The highfin carpsucker is a freshwater fish found in the southeastern and midwestern United States. Its usual habitat is medium to large-size rivers where it is mostly found 1 to 3 metres beneath the surface. It is a silvery fish with a prominent dorsal fin, which grows to an average length of 26.5 centimetres (10 in). It reaches sexual maturity at the age of three and females lay a clutch of about two dozen eggs once a year in the spring or early summer. This fish forages on sandy or gravelly bottoms for such small invertebrates as crustaceans, protozoa and mollusks as well as filamentous algae. Young fish are preyed on by northern pike, muskellunge, walleye and largemouth bass and larger fish are caught by recreational fishermen. The highfin carpsucker competes with catfish and does not thrive in rivers with high levels of siltation.
Pleurocera canaliculata is a species of a freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Pleuroceridae, the hornsnails.
