Question

osmoregulation in fishes​

Answer 1

Answer:

A marine fish has an internal osmotic concentration lower than that of the surrounding seawater, so it tends to lose water and gain salt. It actively excretes salt out from the gills. Some marine fish, like sharks, have adopted a different, efficient mechanism to conserve water, i.e., osmoregulation.
