A study in West Bengal's Rupnarayan river found that Ganges river dolphins adjust their activity based on tide, time of day, and lunar cycle. The month-long research, published in Aquatic Mammals, used acoustic detections to monitor dolphins in a tidal environment influenced by the Bay of Bengal. The area features shifting water levels, currents, and limited vessel traffic, supporting a healthy dolphin population despite human activity.
