How do you study a marine mammal that lives in waters so murky that it can hide from you in plain sight, even in shallow water? On this episode we speak with marine biologist Isha Bopardikar, a researcher using one technique, bioacoustics, to unlock the hidden behaviors of humpback dolphins on the west coast of India.

Mongabay's India bureau recently published a story about her work, “What underwater sounds tell us about marine life”, which noted that although humanity is making the underwater world even noisier through oil and gas exploration, shipping, and other mechanized vessels, today's research tools can still reveal many of the ocean's mysteries.

Bioacoustics combines the study of sound and biology and is increasingly being used to understand marine mammals, so Bopardikar joins us to discuss how, exactly, and play some recordings she's collected of her mysterious cetacean subjects.
