Yes, saltwater gills are different from freshwater gills due to the distinct environments in which they function. Saltwater Fish have gills adapted to excrete excess salt, as they live in a hypertonic environment where water tends to leave their bodies. In contrast, Freshwater Fish gills are designed to absorb salts and retain water, as they inhabit a hypotonic environment where water naturally enters their bodies. These adaptations ensure that each type of fish can maintain proper osmotic balance in their respective habitats.
Fresh and salt water are very different for one key reason, fresh water doesn't contain salt and salt water obviously does. There are different flora and fauna in fresh and salt water for this reason.
yes because of the way their gills get oxygine from the water.
Salt water has salt water in it and is bad for you, fresh water has no salt water in it and is good for you.
Fresh water contains no sign of salt, while on the other hand salt water contains salt
There are many different catfish species, salt water and fresh water.
saltwater has salt in it, freshwater does not.
Salt water contain dissolved sodium chloride; chemical and physical properties are different compared with fresh water.
No, only fish have gills.
There are fish that are commonly called "Bream" in both fresh and salt water.
Currents and thermal gradients aside, salt water is slightly more dense than fresh water, so (at the same depth, for the same temperature) the pressure in salt water will be creater than for fresh water. The difference in pressure will be (pressure in fresh water) x (density of salt water/density of fresh).
Are you serious? One is salty. The other is not.
The primary difference between saltwater crabs and freshwater crabs lies in their physiological adaptations to their respective environments. Saltwater crabs have specialized gills that allow them to extract oxygen from the water, while freshwater crabs have modified gills that are better suited for extracting oxygen from air. Additionally, saltwater crabs have a higher tolerance for salinity levels, whereas freshwater crabs require a lower salinity environment to survive. These adaptations enable each type of crab to thrive in their specific habitat.
