Why can sea mammals drink from the ocean but we can’t?
The reason humans and other land based animals shouldn't drink salt water is because our kidneys can't make our urine saltier than the salt water. This leads to dehydration and eventually death. Whales have larger kidneys that can make saltier urine, so they absorb water from the salt water.

The reason humans and other land based animals shouldn't drink salt water is because our kidneys can't make our urine saltier than the salt water. This leads to dehydration and eventually death. Whales have larger kidneys that can make saltier urine, so they absorb water from the salt water.
