There are many different kinds of marshes, ranging from the prairie potholes to the Everglades, coastal to inland, freshwater to saltwater. All types receive most of their water from surface water, and many marshes are also fed by groundwater.
Shrimp are marine crustaceans that are found on the bottom of the water in nearly every environment around the world. Shrimps are generally tiny in size, with some species of shrimp being so small that many animals cannot see them.hrimp mainly feed on algae and other plant particles along with tiny fish and plankton in the water. One species of shrimp is known to stun it's prey before eating it by making a loud noise with one of it's claws, that makes a snapping sound through the water.
Brine shrimp are able to control how much salt they let into their body tissues better than any other organism in the world thanks mostly to the skin lining of the stomach and the gills. The outer layer of the shrimp is impermeable to water, so the only way for salt water to enter is through the mouth during feeding.As shrimp ingest water, it is absorbed through the stomach lining. Salt is then pumped out the gills instead of going through the digestive tract, as it would in most other animals.hen the surrounding water is less saline, the pumps slow in order to retain some salts within the shrimp. Along with the saline environment, brine shrimp must also deal with low oxygen levels. Humans use a protein called hemoglobin to bind oxygen in our blood. This protein transports oxygen to our muscle cells.
