Though Puck's been calling to Samu since before he was born, it's thought it will 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.

Oh, shark! Is that a shark?

That's a shark, a long one.

Approaching from behind, the family are unaware it's closing.

Samu is in grave danger.

This shark looks like a tiger.
