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.
Having their muscles attached to their exoskeletons is more efficient and allows more muscle connections. Crustaceans also use the same method, but spiders use hydraulic pressure to extend their legs. Unlike insects, though, most aquatic crustaceans are biomineralized with calcium carbonate extracted from the water.rachnids also have two further pairs of appendages that have become adapted for feeding, defense, and sensory perception. They have no antennae or wings. Their body is organized into two tagmata called the prosoma, and the opisthosoma.
