#5 No, penguins don't have an organ that turns seawater into fresh water. Instead, they have a supraorbital gland located above their eyes, which filters salt from their bloodstream. This gland removes excess salt from the blood, and the concentrated salt solution is then expelled, often dripping from their nostrils or sneezed out. This allows penguins to drink seawater without ill effects, as the gland efficiently removes the excess salt.
