Abstract This project is a longitudinal study of the Uca minax fiddler crab species at Spermaceti Cove on Sandy Hook, New Jersey. The purpose of this study is to determine the status of the population, whether or not it is increasing, decreasing, or remaining stable. This has been done by repeating the same method over the past years, and will continue to be repeated in future years. Fiddler crabs are counted at Spermaceti Cove during full and new moon phases at low tides during late spring to early fall, the species' breeding season. After conducting statistical analysis of the quantitative data collected over the years, it shows that the population is remaining stable. As this is a longitudinal study, as more years of data are procured, different conclusions may be drawn by comparing all of the sets of data to each other.
