Oxygen 16 actually evaporates more readily from the ocean than oxygen 18, which leads to a higher concentration of oxygen 18 in ocean water compared to oxygen 16. The other options are true - the nucleus of oxygen 18 contains two more neutrons than oxygen 16, and both isotopes are found in the shells of marine organisms.
