At least one so named specimen called the Coral Catfish.
The majority of catfish are found in freshwater, but not all. There are some found in brackish and marine too, such as Sciades seemanni and Plotosus lineatus.
no
because it dont get the right oxygen in all the seas
Yes! You can find them all the time in fresh water
All octopi, octopuses, live in salt water, but i recommend you ask a professional.
No , some fish live in slat and fresh water but the pet fish you have or want to hve need fresh water.
All water has oxygen!!!! That's why its called h(for hydrogen and) o (for oxygen)
of course is sea water fish conquer more. due to 68 percent of earth is cover in sea water 3 percent is fresh water and glaciers
yes almost all animals require fresh water to live.
I think it all depends on where you live
A few fish that live in fresh water include catfish, trout, and piranha. Nearly all amphibians live in or near fresh water for their whole lives. Pond turtles, snapping turtles, crocodillians, and anacondas are some freshwater reptiles. Freshwater mammals are river otters. Birds like herons, cranes, ducks, geese, and loons live in freshwater ecosystems, too.
the two unusual abilities that a clarias catfish has is: it can live out of water for a long time it lacks pigment (weird, but that's all i can find)
in just about all fresh water
Water beetles live in water, but they can only survive in fresh water or chlorinated water, they can't live in saltwater. There are over 2,000 species of water beetles and they are found in fresh water all over the world.
i think killer whales cant live in fresh water because the need to eat and all of the big fish are in salt water
