Ocean acidification is detrimental to calcium carbonate life. As CO2 is absorbed into the ocean, it has a chemical reaction with water and forms carbonic acid, lowering the pH. This acid reacts with the calcium carbonate that many shellfish need to build their homes and protection, forming a different type of molecule, and depleting the ocean’s calcium carbonate resources. While it was obvious in our lab that our four mollusks, wrinkled drill, cowrie, small oyster, and large oyster, were to be affected by the acids that they were submerged in, it was unclear who would be the worst off. Our results for the hydrochloric acid were fairly inconclusive, on average they were all similar, small and large oysters lost 11% mass, while the cowrie lost
