WAYNE BOARDMAN, BARBARA BLANCHARD, in Reptile Medicine and Surgery (Second Edition), 2006, The three currently recognized Tuatara taxa are the only extant representatives of the suborder Sphenodontia2 (meaning “wedge toothed”). Molecular Phylogenetics and Evolution 29 (1): 1-19 -, Hay, J.M. One such study, conducted by La Flamme et al. This is because settlers brought rats and dogs, which preyed on tuataras and cattle, trampled them. Currently, only two species of tuatara exist, Sphenodon punctatus and Sphenodon guntheri. 1957, Opinion 455.

De naam van de populatie brughagedis van North Brother Island (vroeger: Sphenodon guntheri) is een ode aan de Duitse bioloog Albert Günther. É considerado uma espécie ameaçada desde 1895.O nome tuatara é uma palavra maori que significa dorso espinhoso. The entire population of S. guntheri consists of about 300 individuals living on 1.7 hectares of scrub on the top of North Brother Island; S. punctatus is represented by about 30 populations on small islands off the coast of New Zealand.
