Ever wondered what the rarest animal in the world is? For a
while, the distinction belonged to Lonesome George, the last of his kind of
Pinta Island tortoises, whose once lush habitat had been ravaged by the
introduction of feral goats. Lonesome George, who had the cooler Spanish name
of El Solitario Jorge, a member of the Galápagos Tortoise subspecies C.
n. abingdonii, native to the island of Pinta. Scientists tried to mate
George with other Galápagos tortoise subspecies that are close to his own, but
these attempts failed to produce viable eggs. Unfortunately, Lonesome George
died on June 24, 2012, marking yet another species’ decline into extinction.
The Galápagos tortoise, also known as Chelonoidis nigra or Galápagos giant tortoise are the biggest living tortoise species. They are also the 10th heaviest reptiles that roam the earth, weighing over 880 pounds or 400 kilograms, growing up to 5.9 ft or 1.8 meters in length. Lonesome George, who passed away at 100-years old, was still an adolescent, with a captive Galápagos tortoise once living up to 170-years old. Galápagos giant tortoises only eat plants. They consume berries, lichens, grasses, and cacti that grow around the area. They have also been known to eat Hippomane mancinella, locally known as poison apples, guavas and water ferns. They usually consume about 32–36 kilograms of food a day. However, most food they consume doesn’t pass through nutritional extraction because of inefficient digestion.
While observing these animals, Charles Darwin thought that these animals were deaf since they could not hear him walking behind them. These tortoises are not deaf however, they depend much more on their sense of sight and smell to cope with their surroundings.
