Pinzón Island Giant Tortoise
Chelonoidis duncanensisAlso known as Pinzón Giant Tortoise, Duncan Island Giant Tortoise
These tortoises feature a classic saddleback carapace with an elevated front margin, an adaptation that allows their long necks to reach high arid vegetation on their dry volcanic home. For more than a century, non-native black rats preyed on every wild-laid egg and hatchling, leaving an aging population unable to reproduce until captive head-start programs and a 2012 rat eradication restored natural nesting. Today, young tortoises once again hatch and thrive across Pinzón's rugged lava plains, cementing one of island conservation's greatest recovery successes.

- Safe to observe at a respectful distance.
- What to notice
- Look for a compressed, saddle-shaped shell elevated steeply above the head and front legs in rocky, arid terrain.
- Support conservation
- Keep at least two meters away, remain on guided paths, and never attempt to touch, feed, or corner these slow-moving animals.
Responsible observation
- Distance: Maintain a legal minimum distance of two meters at all times.
- Footwear: Stay strictly on designated trails to avoid crushing concealed burrows or juvenile tortoises.
- Patience: Observe quietly without blocking their walking paths or feeding access.
