Do fish drink water? Do mammals, dolphins, drink water? If so, how do they handle salt water?

Answer 1

Ocean mammals get water from the fish they eat.

Answer 2

Freshwater fish do not actively drink water, yet take up the water by way of their epidermis and gills. on the different hand, saltwater fish do actively drink sea water. Their gills technique the water and take out the salt. The salmon is an enticing occasion of a fish that lives in the two sparkling and salt water, and hence, they have the features of the two varieties of fish. Salmon are born in sparkling water, and migrate to the sea. whilst residing in the sea, they drink saltwater by means of establishing their mouth; their gills then rid their bodies of the salt and minerals. while the salmon enters freshwater streams to spawn, they stop eating the water and actually take up it by way of osmosis (osmosis ability that the water passes in the process the cells of the fish's epidermis into its physique).

Answer 3

All animals and plants need water.
Ocean animals have organs that remove salt from their systems and excrete it. Different species have different methods. Imagine being a mollusk in the Ocean! What would happen if you put a land slug in salt water, eh? But the sea slugs thrive there.

Answer 4

Dolphins’ main prey (fish and squid), contains large amounts of water and so dolphins obtain water from their food. Fish, such as herring and mackerel can be made up of as much as 80% moisture, whilst moisture levels in squid are even higher. In addition, dolphins don’t actually need to take in very much fluid because, unlike us, their skin is impermeable and they don’t lose water by sweating.

and for fish
