Web4 Oct 2024 · Fish do absorb water through their skin and gills in a process called osmosis. Osmosis is the flow of water across membranes from areas of low concentration of dissolved things (solutes) to areas of high concentration. It serves to equalize the concentrations in the two areas. WebA salt water fish lives in water that is very salty (obviously), much saltier than the inside of the fish! This means that it is harder for a saltwater fish to maintain enough water inside its body because the water is constantly flowing from the inside of the fish to the salt water outside the fish due to osmosis.

A good sign of a freshly-caught fish is a bright red gill. WebOsmoregulators actively control salt concentrations despite the salt concentrations in the environment. An example is freshwater fish. The gills actively uptake salt from the environment by the use of mitochondria-rich cells.
