Five Common Snook

Snook have the ability to adapt to sudden changes in salinity. This process is called osmoregulation. They can even move from a saltwater to a  freshwater environment, adapting to sudden  changes in salinity with the help of special cells called chloride cells, which are located within their gills. These snook were found in a freshwater  spring north of Tampa Bay.
