Conservation overview

The Galápagos giant tortoise is among the largest tortoises in the world and can live well over a century. The complex of forms is generally assessed as Vulnerable, with some island populations more imperilled.

Different islands evolved distinct shell shapes, which helped inspire ideas about evolution.

Range & habitat

The Galápagos Islands of Ecuador, with different forms on different islands.

Major threats

Threats below are drawn from the authoritative sources listed on this page. For the current, complete assessment, see the IUCN Red List.

  • Historical exploitation by sailors
  • Introduced animals (goats, rats, pigs)
  • Past habitat damage

Why it matters

An icon of the Galápagos and of evolutionary science, the giant tortoise is a flagship for island restoration and the removal of introduced species.

Frequently Asked Questions

How long do Galápagos giant tortoises live?
They are among the longest-lived land animals, frequently living over 100 years, and some captive individuals have reached well beyond that.
Why are Galápagos tortoises important to science?
The way shell shape and size vary between islands helped inform early ideas about how species adapt to local conditions — a cornerstone of evolutionary thinking. See the IUCN Red List for conservation status.
