swallow plenty of sea water to increase amount of water in the body
have chloride secretory cells in their gills to remove excess salts
few glomeruli thus slow filtration rate in the kidneys
eliminate nitrogenous wastes in form of trimethylamine oxide which requires little water for elimination.
Fresh water
Both kinds of fish can live in a delta area. The line between salt water fish and fresh water fish seems to be getting blurrier. Sharks and other typically salt water fish are found many miles up stream in rivers that empty into the ocean. It appears that salt water fish adapt better than fresh water fish as the fish found in fresh water are not found out at sea.
An example of osmosis in animals is the movement of water through a fish's gills. The fish's body is saltier than the surrounding water, so water moves from an area of lower salt concentration (the water) to an area of higher salt concentration (the fish's body) to establish equilibrium. This helps the fish maintain its internal salt balance.
it's actually both. there are fresh water puffers and saltwater puffers and brackish water puffers. the fresh water ones tend to be large (2ft for some species) for a more accurate answer i need a species name for the puffer
Yes, a black bass is a type of fresh water fish.
Why don't you figure it out yourself
Fresh water fish do not drink water, they absorbed it through their skin, like osmosis. Sea water fish do drink water, and excrete the salt through their gills. The salmon, which lives in both in environments, gets its water like a fresh water fish when in fresh water and like a sea water fish when in the sea.
Fresh water
I guess you mean freshwater when you write "clearwater". Ocean dwelling fish evolved to live in water containing high quantities of salt and have a skin and coating that is designed to protect them in that kind of water. In fresh water their natural protection will not work properly and osmosis will happen and the fish will die. There are species of fish that can and do live in both fresh and sea water.
fresh water .my fish are 16 yrs old
Because their blood chemistry is designed to be in homeostasis with a saline medium. In fresh water, water will enter the fishes tissues and kill it. However some fish (eels and salmon) have evolved to live in both environments.
Fresh water fish survive just as well as fresh water fish. Maybe this question isn't the one that you actually meant to ask?
Rivers,lakes.ponds,any fresh water source or there are fresh water fish breeders
yes what are the fresh water fish that lives with gold fish
Fish are the perfect example of osmosis in living organisms. Salt Water fish are constantly drinking because they are always losing water to their environments. On the other hand, fresh water fish almost never need to drink because they are constantly absorbing water through their skin. Could somebody improve this because this doesn't exactly say how osmosis actually happens in living things it just says about salt fish which might have soemthing to do with it/ / Osmosis is when water moves from an area of high concentration to low, which is why salt water fish lose water ( it's less concentrated around them, because of the salt, than in them)
No , some fish live in slat and fresh water but the pet fish you have or want to hve need fresh water.
Well it depends on the fish. If it is a fresh water fish then it lives in fresh water, salt water fish live in salt water.
