Abstract

Reduction of intestinal lumen osmotic pressure by the formation of Ca(Mg)CO, "ichthyocarbonate," is essential for osmoregulation by the only vertebrate group, ray-finned fishes, widely capable of hydrating by ingesting seawater. Ichthyocarbonate formation and excretion are under elaborate physiological control and play an important, yet still poorly defined, role in the oceanic carbon cycle.

摘要

通过形成 Ca(Mg)CO3“鱼碳酸钙”来降低肠道腔渗透压，对于唯一能够通过摄入海水进行水合作用的脊椎动物群体——硬骨鱼类来说，是渗透调节所必需的。鱼碳酸钙的形成和排泄受到精细的生理控制，在海洋碳循环中发挥着重要但仍未充分定义的作用。
