Badly weakened he's chaperoned towards the harbour entrance

But he's not out of trouble yet

First he must negotiate the rocky heads of the bay

His sensitive skin never designed to touch rock is badly lacerated

He's through and back into the safety of the endless blue

The sperm whales' story

Sums up the difficulties of surviving in this world of extremes

They succeed thanks to their great stamina and extraordinary design

But at times even the whales struggle to

Cope with the challenges of this vast ocean
