This shrinkage occurs does to the movement of water out of the cell and through the cell membrane.this phenomenon is called plasmolysis.
The movement of water out of this cell occurs through osmosis.osmosis is the movement of water from a region of high concentration of solute to a region of low concentration of solute, through a semi-permeable membrane.
In this case,sea water has a higher concentration of solute (hypertonic) and the blood cells has a lower concentration(hypotonic) .the cell membrane serves as the semi-permeable membrane and and a result water moves out of the cell
