Although resembling a lizard, the tuatara is not one; it belongs to the order Rhynchocephalia, distinct from squamates (lizards and snakes). It is often referred to as a 'living fossil.'

Translation Traps (for Russian speakers)
- Do not translate as 'ящерица' (lizard) without qualification, as it is a distinct order. 'Гаттерия' is the standard Russian equivalent, not a descriptive phrase.
Common Mistakes
- Pronouncing it /ˈtjuːətɛrə/ (tyoo-a-terra).
- Referring to it as a 'type of lizard.'
- Misspelling as 'tutara' or 'tuataria'.
