Final answer:
Marine reptiles, such as sea turtles, have specialized salt glands that produce salty tears to excrete excess sodium chloride (NaCl).
Step-by-step explanation:
Salt glands are specialized organs that help marine organisms deal with the high salinity of their environment. They function to excrete excess salts, like NaCl, which these animals accumulate by drinking seawater or eating salty foods. Among the choices given, marine reptiles such as sea turtles are well-known for having salt glands. These glands can be near the eyes, as in the case of sea turtles that produce salty tears to remove excess salt. Other marine organisms have different osmoregulatory adaptations but do not have specialized salt glands like reptiles.
