Rectal Gland - epithelial tissue gland - concentrates & secretes excess Na & Cl in sharks. Large shark liver produces copious amounts of urea, making the shark hyperosmotic to seawater, & thus a shark acts like a fresh water fish, constantly gaining water. Excess salts are concentrated by the rectal gland and secreted.
