Abstract

The rectal glands of elasmobranchs perform the function of salt-excreting organs. These glands are smaller and show regressive changes in specimens of the bull shark, Carcharhinus leucas, found in fresh-water environment, compared with specimens of this and other species from a marine habitat.
