The various species of fish found in oceans, lakes, rivers and streams have evolved over millions of years and have adapted to their preferred environments over long periods of time. Fish are categorized according to their salinity tolerance. Fish that can tolerate only very narrow ranges of salinity (such Freshwater Fish as goldfish and such Saltwater Fish as tuna) are known as stenohaline species. These fish die in waters having a salinity that differs from that in their natural environments.
The only fish I know of that lives in both is Pacific salmon. Salmon are born and they reproduce in the safety of freshwater but spend the rest of their lives in the oceans. This type of fish (fresh and salt water) are called anadromous.
Freshwater contains small traces of pepper, therefore making saltwater fish sneeze in freshwater, because they are not accustomed to it.
Some can live in both.
yes, they can survive in fresh water as well as saline water
by eating animals that contain freshwater
A saltwater crocodile would not survive in fresh water. Salt water animals need the salt to keep them alive and to nourish them.
the aquatic animals and plants also known as water animals and plants or marine animals and plants can survive in water.as our body is designed to live in a particular area, environment the same way the water animals and plants are also designed to live in water.most of them have gills or special organs which helps them to breathe in water as water also consists of air.this is how plants and animals survive in water.
Yes. Some animals can survive with no water.
they swim to the bottom of the water in high tides\
Fresh water animals.
Damsel fish are OK in a Marine (sea water) environment. They will not survive in fresh water.
they can if the ocean is fresh water
No, cougars cannot drink ocean water when they have no fresh water. Like humans, cougars require fresh water in order to live.
The body needs water to survive and can only go 3 days without it. Animals and plants also need water. So, a fresh clean water supply was necessary.
