Which animals eat sludge worms in the food chain?
Geographic Range Acipenser fulvescens occurs in the freshwaters of North America from the Hudson Bay through the Mississippi River drainages to Alabama. It is found along the Great Lakes – St. Lawrence River drainage and in large lakes in New York and Vermont, including Cayuga Lake and Lake Champlain. Biogeographic Regions: nearctic (native ). Habitat The lake sturgeon is a fish of temperate waters and is found only in the Northern Hemisphere in North America. Their habitat is usually on the bottom of a riverbed or lake. Acipenser fulvescens prefer a river or lake bottom that has clear sand or gravel. (Herald 1971) Aquatic Biomes: lakes and ponds; rivers and streams. Physical Description Mass 90 kg (average) (198 lbs) This fish has a skeleton partly of bone and partly of cartilage. Their slender bodies are covered with rows of bony plates. Beneath the projecting snout there is a small, toothless mouth with thick, sucking lips. There are four barbels (whiskers) in front of the mouth tha
Ecologically, the worms are important as a source of food for leeches, crustaceans, insects, and fish. Tubifex are sold as fish-food in both live and freeze-dried, pelletised forms. While the worms are relatively easy to culture, they can take up to a month before they can be harvested. Tubifex tubifex, also called the sludge worm, sewage worm, or lime snake, is a species of tubificid segmented worm that inhabits the sediments of lakes and rivers on several continents. T. tubifex probably includes several species, but distinguishing between them is difficult because the reproductive organs, commonly used in species identification, are resorbed after mating, and because the external characteristics of the worm vary with changes in salinity. These worms ingest sediments, selectively digest bacteria, and absorb molecules through the body wall.
