Mumbai is one of the most populated coastal metropolitan cities in the world. Even with a high population density, the coastal ecosystem shows diverse organisms. However, due to the anthropogenic activities, this diversity is under threat. The present study aims to understand the diversity of sandy shore of Girgaon Chowpatty and rocky shore of Haji Ali. This work was carried out during the low tide in the intertidal region of both the sites. Combination of quadrant method and random walks was used to collect the data. The effect of human invasion was seen during the study. Despite the high footfall and anthropogenic activity, the intertidal region was thriving with organisms.
