Galápagos Giant Tortoise

These ginormous creatures also make their home on the Galápagos Islands, and since they can grow up to 59 inches and weigh 550 pounds, they’re likely not going anywhere else. ‘The giant tortoise has thick, sturdy legs to carry its weight, but will spend a lot of time lying down to conserve energy,’ Diez says.

‘While their shells may look heavy, they are actually made up of honeycomb structures that enclose small air chambers, making it easier for the tortoise to carry the shell without difficulty.’ Perhaps taking things on the slow side and storing up energy is what helps give them a long life—up to 100 years.
