📖 1. Overview
The Tuatara is a reptile living only on offshore islands of New Zealand, though it once lived across the entire New Zealand mainland.
🦴 2. Anatomy & Morphology
Adult males measure about 0.5 m in length and weigh up to 1.5 kg. They continue growing until about age 35.
🔍 3. Ecology & Behavior
It mainly eats invertebrates such as beetles, weta, earthworms, and spiders, and also eats lizards and seabird eggs and chicks. Because it reproduces slowly, eggs and young are easily lost when predators such as rats are present. Its average lifespan is about 60 years, up to a maximum of 100 years.
🇰🇷 4. Connection to Korea
No direct record connecting this species to Korea has been found.
