What kind of shelter does a tuatara lizard have?

Tuatara are not lizards. They are lizard-like reptiles, endemic to New Zealand, but they are not members of any lizard family.

Tuatara live in broad-leafed forest land and grasslands near seabird colonies, where the birds have dug burrows. They shelter under rocks, in rock crevices, amongst shrubbery and bark, and in burrows.
