Dhaka - Researchers have identified waters along Bangladesh's coast and deep in the Bay of Bengal as one of the richest areas on Earth for cetacean diversity.
An amazing array of dolphins and whales live in these areas, the US-based Wildlife Conservation Society and Bangladesh's Cetacean Diversity Project said after conducting a joint study over the past six years.
But scientists at the same time warned that the habitats of these aquatic mammals are increasingly in danger because of declining freshwater flows from the Ganges River and global climate change.
