Do Sea Mammals drink saltwater. If so, is there a process by which they filter out the salt?

Question

And do different sea mammals do it differently. Like sea otters and dolphins. Whales and Walruses.

Answer 1

Humans can remove some salt with the kidneys but excessive salt, as in sea water, is too much for them to cope with. Sea mammals have evolved better kidneys that are able to cope with the excessive salt. They take in a lot of sea water with their food and have to get rid of it. the kidneys do the job efficiently.

Most marine mammals are happy in fresh or salt water and you will find them, on occasion, swimming up rivers. This helps to rid them of skin parasites that die in fresh water.

Seabirds have a gland in their skull that removes excess salt which trickles out through the nostrils.

Answer 2

Sea animals do not drink salt water. Their hydration mostly occurs by eating other animals. The saltwater that enters their body is filtered out by their kidneys. The delicate internal balance that filters out the salt is also why you can't put salt-water animals in fresh water and vice-versa.

Answer 3

even inspite of the indisputable fact that some marine mammals are customary to drink seawater a minimum of on social accumulating, this is not properly commonplace that they immediately do so. they produce different innovations: sea-living mammals can get water via their food, and that they'd produce it internally from the metabolic breakdown of food (water is between the by ability of-products of carbohydrate and fat metabolism).
