Pteropods are very small free-floating marine snails that play a very big part in oceanic ecosystems. Although tiny, these creatures are extremely important because they make up an important part of the oceanic food web. Scientists have seen the negative effects of ocean acidification on pteropods and are studying these organisms to better understand the problem. This slideshow is part of our Ocean Acidification Education series.
