Interesting facts

By eating plants and spreading seeds, these tortoises act like tiny gardeners for their islands!

Early sailors used them for fresh food and even as living compasses on their ships!

They can store water in their bladders, letting them go a year without a drink!

Tortoises bask in the sun to warm their cold blood, which helps them digest their leafy meals!

Special abilities

Galapagos Tortoises can live over a century because of their slow metabolism, helping them survive long periods without food.

Galapagos Tortoises have a huge, bony shell that helps protect their soft body from predators and impacts.

Certain tortoise types can stretch their long necks high to reach leaves, adapting their shell shape for foraging.
