Osmoregulation in Marine Mammals [PDF]

open access: yesJournal of Experimental Biology, 2001
SUMMARY Osmoregulation in marine mammals has been investigated for over a century; however, a review of recent advances in our understanding of water and electrolyte balance and of renal function in marine mammals is warranted. The following topics are discussed: (i) kidney structure and urine concentrating ability, (ii) sources of water,
