Measurements were made of the partitioning of total body water in the sea lamprey, Petromyzon marinus, between intracellular and extracellular compartments and the division of the latter into interstitial fluid and plasma. The apportionment of body water in agnathans is very similar to that in elasmobranchs, and both of these primitive groups differ from what is known of the more advanced teleosts.
