 The research team have been out since dawn looking for Puck.  It's now the height of the shark season, Semu, who's been born at the worst time. 

“We've been waiting for Puck to have a calf¹, and now finally she's finally here,  we're all too so relieved that we can actually see the calf and then the calf is actually good and healthy.”

 

Though Puck has been calling to Semu since before he was born, It's thought it would take him a week to learn her call.  He swims very close to Puck's head, listening intently to her whistle. The one thing he must avoid is getting separated from her, this would mean certain death. Puck may not eat for a week, she cannot risk losing sight of him for a moment.
