| Research Abstract |
In this study, we found that guanylin, adrenomedullin and relaxin form a family of diversified members in teleost fishes and play important roles in osmoregulation, particularly in seawater adaptation. We also found that natriuretic peptides that suppress drinking and angiotensin that induces drinking act on the area postrema in the medulla oblongata to regulate reflex swallowing in aquatic fishes, which is in contrast to terrestrial animals where they regulate thirst by acting on the forebrain.
