WebAlthough everyone knows that seawater is salty, few know that even small variations in ocean surface salinity (i.e., concentration of dissolved salts) can have dramatic effects on the water cycle and ocean circulation. … Web15 dec. 2009 · Teleosts address this challenge by drinking seawater and taking up both salt and water across the gut, while excess sodium and chloride are secreted by the gill. Thus, the transition from freshwater to seawater requires that the gill reverse its function from an ion uptake to a salt secretory organ.
