After seeing Jurassic Park, we are all amazed 51 the size of those ancient creatures, the dinosaurs. However, dinosaurs were not the largest animals that have ever lived on earth; this 52 goes to the blue whale. These marine mammals are long and slender in shape. Until the 19th century, they had had no problem 53 and living by themselves. However, in the 20th century, they were hunted outrageously by whalers and decreased rapidly in number, until the international community stepped in to save them from extinction in the year 1966. Blue whales 54 mostly on krill to fill their stomachs, and in a single day an adult blue whale can eat 55 40 million krill. And at the beginning of winter, after a pregnancy lasting from ten to twelve months, the females give birth—typically once every two to three years.
