In summary, it is evident that teleost and elasmobranch fish respond to extra-cellular dehydration by increasing drinking rate mediated by an increase in circulating levels of ANG II. However, although the primary stimulus for drinking may be the same, clearly the mechanisms involved in regulating ion and water balance are entirely different. In order to maintain ion and water balance in the face of cellular and extra-cellular dehydration, the integration and hormonal control of renal and extra-renal function in elasmobranchs has developed in a very different manner to that described for teleost fish.
