Close-up on a venerable Galápagos tortoise. This one’s ability to raise its head high is more than just a good photo pose — it also gives us a clue about its habitat.
Tortoises who live on greener islands with lots of shallow water have broader shell brims that keep their heads closer to the ground. This tortoise, who can lift its head to browse for a wider range of leaves, likely lives on a drier part of Santa Cruz island.
