But, due to dramatic population declines as a result of overfishing and withering syndrome, Black Abalones have been classified as critically endangered by the IUCN. Cassandra Brooks interviews Amy Henry, an intern looking for Black Abalones in the Golden Gate National Recreation Area and Point Reyes National Seashore.

This incredible diversity of life evolved over millions of years, as animals figured out ways to pull calcium and carbonate ions from the water to build shells and skeletons. But all of this is changing.
