Watch this Humpback Whale calf blissfully playing on a windy day in Mozambique. Fin slapping behaviour is a way that whales communicate with each other, and the sounds carry further on windy days. I watched this calf cruising like this in the shallows for almost an hour before her mum came to get her and they both descended into the deep. #humpbackwhale #whales #dronestagram #wildlifephotography #yourshotphotographer #naturephotography #marineconservation
