What is it about their biology that allows them to do that?

If possible, please provide references. I'd like to give ten points to the person who gets it right, but I need verification.

sea otters have extra large kidneys that get rid of the salt in the sea water the drink, but they also moisture from breathing the moist air and many of the foods they eat......they dont have gills
Whales get fresh water much of the same way

Animal includes mammals. The Blue whale is a mammal. Next largest animal is the Whale Shark (which is a fish and also an animal)

Dude, I am 13 and i know!!! They have what you call sea lungs that filter keep out all the salt from entering into their lungs and stomach. Since they have the filter in their mouth it holds all the salt. eventually the salt disintegrates.

A lot of them like to wait till it rains to get fresh water near the surface too.

They have special "salt filters" before their lungs. Before seawater enters their lungs, these salt filters filter the salt present in the water. So the gills receive a less less salty water and the rest of the processes proceeds.
