Habitat. The main difference between freshwater and marine life is the habitat they come from in the wild. Freshwater fish live in streams, rivers and lakes that have salinity of less than 0.05 percent. ... These are also known as saltwater fish because they can only stay alive in waters with high salinity levels.

Salt water is water that contains a certain amount of salts. About 71% of the earth is covered with salt water. ... Freshwater is water with a dissolved salt concentration of less than 1%.

Shrimp come from both fresh and salt water and can live in both cold and warm waters; if they came from cold waters, then they will be smaller in size. There are more salt-water than fresh-water species of shrimp. Prawns come from fresh water, and are much larger and meatier than shrimp, like a langoustine.

Freshwater ecosystems are the ecosystems in freshwater bodies, including rivers, lakes, ponds, streams, etc. In comparison, saltwater ecosystems are the marine ecosystems or ecosystems in oceans and seas. ... The life in these two ecosystems has adapted to these different salt contents.

As a result, most saltwater fish constantly lose water through their gills and skin. Because the fish is losing water, it must drink a lot to stay hydrated-but salty seawater is the only water around. To get rid of excess salt, the fish's kidneys pump lots of salt into its urine.

Prawns often reside in calm waters where they can perch on plants or rocks and comfortably lay their eggs. Summary Prawns and shrimp reside in both fresh and salt water. However, the majority of shrimp are found in salt water while most prawns live in fresh water.

In the case of saltwater/marine plants, the solute concentration within the cytosol of cells will be relatively higher than in freshwater, since saltwater has a higher concentration of solutes (mainly dissolved salts) than freshwater.

The most easily noticed difference between the species (besides size) is the shape of the head and teeth. Freshwater crocodiles have longer and thinner snouts, with a straight jawline, and all their teeth nearly equal in size. Saltwater crocodiles have a broad, powerful-looking snout, with an uneven jawline.

Salt water is water that contains a certain amount of salts. ... Salt water can be found everywhere on the surface of the earth, in the oceans, in rivers and in saltwater ponds. About 71% of the earth is covered with salt water. Freshwater is water with a dissolved salt concentration of less than 1%.

In a word: no! Saltwater has a lot of beneficial properties for dogs, just like it does for humans. That said, salt water is naturally much more drying than freshwater. Remember that any kind of repeated exposure to either fresh or saltwater and/or intense heat or sun can lead to skin and coat issues down the road.

Most species live beside water, but river otters usually enter it only to hunt or travel, otherwise spending much of their time on land to prevent their fur becoming waterlogged. Sea otters are considerably more aquatic and live in the ocean for most of their lives.

Alligators are freshwater creatures and do not live in saltwater. ... The only exception I know of with gators in canals is in Port Charlotte where some canals are a long way from saltwater and have a freshwater influence at the top end. There you might find a gator or two but seldom do you hear of a problem.
