Because they need some of the bacteria in the salt water to live. the fresh water doesen't provide the certin bacteria that the other water has.
yes because if there was no any there will only be herbivore in the fresh water
Why do humans not live in water? The same concept. We can't breathe in water they can't live in fresh water.
to keep them fresh. plants need water to live.
Otters are found throughout the world on all continents except for Australia and Antarctica. They live near rivers, springs, streams, lakes and other inland waterways, while sea otters live along the coastlines.
Whales and porpoises live their entire lives in salt water.Manatees inhabit tidal zones; they can spend a lot of time in salt water, but they must find fresh water to drink.Seals, sea lions and walruses are considered semi-aquatic. They are born on land and only spend part of their time in the water.Sea otters can walk on land, but are usually born in the ocean and spend all their time there. Marine otters are a similar species; little is known of their behavior, but they do seem to spend more time on land than sea otters.
There are both freshwater (river otters) and salt water otters.
they live in salt and fres
River otters live in the shores of fresh water regions. River otters live on river shores. River otters hold there breath when going under water. They also use sticks and branches to build a dam in the water.

Yes. Otters live in and around water. They're aquatic and they are found in both fresh and salt water. About a dozen different species inhabit the planet. A link can be found below for more information.
lots live in water like fishes and sea mammals (otters, seals, dolphins, sealions,whales. i.e) but it depends on what water it is, fresh or sea (salty)
most likely not. they'er "salt water" shrimps so they cant live in fresh water. sorry if that didnt answer your question.
In the water
i think killer whales cant live in fresh water because the need to eat and all of the big fish are in salt water
Otters are a semi-aquatic mammal. So they don't live exclusively in water.
There are algae, corals, seaweed, etc., etc.,etc.
