osmoregulator An animal that maintains a constant internal osmotic environment in spite of changes in its external environment. Vertebrates and some aquatic invertebrates, especially freshwater invertebrates, expend energy on osmoregulation to maintain cell volumes and achieve optimum conditions for metabolism (i.e. homeostasis). Compare osmoconformer.
