Today's guest is Mahi Mankeshwar - a cetacean biologist who has one of the most natural affinities to the marine space that I've ever encountered. She was one of the first people to systematically document the diversity of marine mammals around the Andaman and Nicobar Islands, with a focus on cetaceans - that is, dolphins and whales. Her work across the islands has led to some of the most fantastic sightings and records of these incredible animals for whom Indian waters are home. And from the sound of it, she's only getting started.
