This 28 July 2018 BBC video says about itself:
When a new baby dolphin is born, his family reunites around him to welcome him as one of them.
In a stunning new insight into the lives of wild dolphins, this film follows six remarkable months in the life of the ‘Beachies’: a family of six dolphins led by mother-to-be Puck, who live in the shark-infested waters of Western Australia‘s Shark Bay. Using the latest miniature cameras to eavesdrop on the Beachies’ underwater lives, this moving story follows Puck and the challenges she faces bringing up her newborn calf Samu. From learning to fish, to the ever-present threat of a shark attack, no day is ever the same. Including rarely seen footage of young dolphins and revelatory new behaviour, this is a heart-warming and emotional portrayal of one of the ocean’s most revered creatures.
