A Horizon presentation of seven programmes on animal life.
Plant life cannot sustain all the creatures in the sea. Animal life can and does.
In the sea the struggle to survive begins at birth. For many species only an enormous birth rate can ensure that some will live to carry on the species. The overall odds of survival are often incredibly small in the fish-eat-fish world of the oceans.
'Survival in the Sea', the second Eye on Life film, examines this week the complex world of life and death under water.
