turtles, like majority of reptiles use glands located in their nasal passages, tear ducts, etc to secrete excess salt
"They can drink salt water because their supraorbital gland filters excess salt from the bloodstream. The salt is excreted in a concentrated fluid from the nasal passages." http://en.wikipedia.org/wiki/Supraorbital_gland
The secret of the gull's ability to survive drinking salt water lies in a pair of glands in the head, but their function was not eluciadated until a few years ago. Each gland consists of thousands of minute tubes arranged like the bristles on a bottle brush. Where the handle of the brush would be is a central tube communicating with the nasal cavity. A rich supply of fine blood vessels surrounds the gland, which extracts the salt from the blood.
They have salt glands which prevent an excessive amount of salt in the water from irritating the skin. The salt glands are found on the penguin's facial region.
The thyroid gland is often imaged using a salt of iodine-131 as this gland has a high uptake of iodine.
the lack of salt is called Goiter, an enlargement of the thyroid gland.
