How taking a picture of a whale's tail can help track the majestic mammals

CBC Newfoundland Morning

Anyone who's been whale watching from a boat or from land knows what a thrill it is to see a whale's fluke as they dive deep into the water. But what you might not know is that the underside of a humpback whale tail is unique! In fact, the fluke can be used to identify that specific whale. A group called Happy Whale has a website that lets you upload images and get information about whales and where they've been. Ted Cheeseman is the co-founder and director of Happy Whale.
