They eat things like cacti, grasses, leaves, lichens and berries. They can eat an average of kilograms lb. They get most of their moisture from the sap in the vegetation and dew from the ground, therefore they can spend a lot of time without drinking, and when they get water they can store it in their bladders and the bottom of their neck for long periods of time.

They can even go 18 months without having food and water because they can break down their body fat to produce water as a by-product. Habitat The Galapagos tortoises are native to seven of the Galapagos islands west of the Ecuadorian mainland. The shell shapes and sizes of the tortoises vary between populations depending on the islands that they live on.

On the islands with humid highlands the tortoises have a dome shaped shell, they have shorted necks and they are larger.
