Environment and Salinity Tolerance in the Genus Fundulus
- R. W. Griffith
- Environmental Science, Biology
- 13 June 1974
It is suggested that freshwater species of Fundulus were derived from fully euryhaline ancestors which gradually lost the ability to live in sea water during extended isolation from brackish or marine environments.
Branchial Reduction and Renal Stimulation of (Na+, K+)-ATPase by Prolactin in Hypophysectomized Killifish in Fresh Water

Maetz and his associates have shown that a primary osmoregulatory function of prolactin is the reduction of extrarenal sodium outflux which is uncontrolled, or poorly controlled, after removal of the hypophysis.
Osmoregulation in Elasmobranchs

Osmoregulatory mechanisms were examined in major groups of fishes including hagfish, holocephalans, elasmobranchs, the coelacanth, and ray-fin fishes. Four main patterns of body fluid composition…
Guppies, toadfish, lungfish, coelacanths and frogs: a scenario for the evolution of urea retention in fishes
- R. W. Griffith
- Biology, Environmental ScienceEnvironmental Biology of Fishes
- 1 September 1991
A scenario is proposed that suggests how ureosmotic regulation could have evolved in Latimeria and other fishes, a classic marine ureOSmotic regulator in which urea is used as an osmolyte that allows osmotic equilibrium with sea water while maintaining low ion levels.

SERUM COMPOSITION OF FRESHWATER STRINGRAYS (POTAMOTRYGONIDAE) ADAPTED TO FRESH AND DILUTE SEA WATER
- R. W. Griffith, P. Pang, A. K. Srivastava, G. Pickford
- Environmental Science
- 1 April 1973
Freshwater stingrays are unique among elasmobranchs in possessing significant amounts of a protein with the electrophoretic mobility of human mobility, and the trend to increase in a saline environment was not osmotically significant.
