- Wow! Tuatara are the last survivors of an entire ancient reptile group called Rhynchocephalia!
- Wow! Tuatara eggs take over a year to hatch, the longest incubation of any reptile!

## Special abilities

- **Third Eye Vision:** Tuatara has a light-sensitive 'third eye' on its head that helps them regulate their body temperature and understand day-night cycles.
- **Chilly Chiller:** Tuatara can stay active in colder temperatures than most reptiles because of their slow metabolism, helping them hunt at night.
- **Ancient Lineage:** Tuatara has unique genetic traits that link them directly to prehistoric reptiles, helping scientists understand dinosaur-era life.

## Ecological connections

- **Hunts:** tree wētā (*Hemideina crassidens*) — A large, flightless insect often eaten by tuatara.
- **Shelter:** grey-faced petrel (*Pterodroma macroptera*) — Tuatara often share burrows with this seabird.
- **Eaten by:** Pacific rat (kiore) (*Rattus exulans*) — Introduced rats were a major threat, preying on tuatara eggs and juveniles.
