Tension at the surface of unfertilized sea‐urchin eggs was measured at various temperatures by compression method. It was confirmed that the tension definitely decreases with a rise in temperature. This indicates that (1) the tension at the surface as determined with the compression method is due solely to the plasma membrane, and (2) the membrane is fluid in nature.
