The Blue Whale is the biggest animal on earth, weighing up to 150 tons and it eats only krill, which are shrimp-like creatures less than half an inch long. Mind you this gentle giant can eat several million of them in one day so if you are a krill you might want to take note of this. Also notice on the attached sketch sheet, the endangered Right Whale, dwindling in numbers in recent years. Many Right Whales are injured in the North Atlantic and elsewhere by passing ships. Despite humane cries to end the slaughter of many endangered species of whales, the hunt still goes on. When will humanity learn that the balance of life in our precious oceans is a delicate one - upon which we are conducting a dangerous experiment, in the very test tube where we are living.
