Being massive can have its advantages but it brings equally immense challenges to survive. Big bodies need more fuel and more space, and can attract unwanted attention.
Take the world’s largest lizard, the Komodo dragon, whose huge appetite means it must take on prey 10 times its weight. Or the tallest of them all, the giraffe, which with such a long neck must control immense blood pressure. From the 150-ton blue whale—which can suck up to four tons of krill a day—to Japan’s finger-length giant hornets that can decimate a hive of 30,000 bees to feed on their larvae, nature’s biggest beasts must go to extraordinary lengths to thrive.
These are their epic survival stories.
