Just curious as to why fish and other sea creatures that live in salt water are not overly salty when ingested? I would think they would absorb most of the salt they live and breathe in.
Edit: added the word overly
In: Biology
Water concentration inside a fish is higher than in the ocean itself because the ocean is so salty. As a result, most saltwater fish constantly lose water through their gills and skin. To get rid of excess salt, the fish’s kidneys pump lots of salt into its urine.
tldr; they piss it out
