The biodiversity of aquatic organisms of Long Island is expected to be divergent in different bodies of water. The purpose of this study is to use DNA to determine what organisms are present on the North and South Shores of Long Island. The North Shore is anticipated to show less biodiversity because the waters off this shore are more polluted than that of the South Shore. DNA will be isolated, amplified using the cytochrome c oxidase subunit I primer and sent for sequences. The sequences will be analyzed using DNA subway and the diversity of organisms will be compared. This will result is the ability to see if one region is more diverse than the other.
