Tuatara are regarded as the messengers of Whiro, the god of death and disaster.

 New Zealand's Tuatara
Tuatara are the last surviving members of a family which stretches right back to the Mesozoic, to the beginning of the Age of Reptiles.
Tuatara can co-exist with Kiore under favourable conditions, and does today on some Tuatara islands with a greatly reduced population, but when conditions are less favourable looses the battle, and on at least one island has become extinct as a result of Kiore activity.
Tuatara is known scientifically as a 'living fossil', a distinction shared with a few other species including the coelacanth fish, the horseshoe crab, and the native frogs of New Zealand, which have apparently changed little from extraordinarily ancient origins.

Tuatara are rare, medium-sized reptiles (adults ranging from about 300g to 1000g) found only in New Zealand, They are the only extant members of the Order Sphenodontia, which was well represented by many species during the age of the dinosaurs, some 200 million years ago.
Tuatara are therefore of huge international interest to biologists and are also recognised internationally and within New Zealand as species in need of active conservation management.
The islands are usually occupied by colonies of breeding seabirds that contribute to the fertility and hence the richness of invertebrate and lizard fauna needed by tuatara.

 Science News: Return of the tuatara: a relict from the age of dinosaurs gets a human assist - reptile conservation ...
Tuatara, spiny cousins of lizards, are among the coldest of the cold-blooded reptiles, living on brisk, wind-whipped islands off the mainland of New Zealand.
"Tuatara are sit-and-wait predators," says Daugherty "They sit in front of their burrow all night, in a sort of advertising display [to ward off] other tuatara, and hoping a food item will wander by" They aren't fussy about what they eat: skinks, worms, giant weta crickets, even young tuatara or birds--anything that moves.
On one island, tuatara, that were individually identified in the 1940s as fully grown adults are "still alive, still breeding, still the same size, and looking right in the pink of health," says Daugherty.

 Tuatara
The main cause of the tuatara decline is the rat (in its three forms), the Maori 'kiore' being the most likely culprit in decimating populations.
Tuatara can take up to 2 years to produce an egg, and then another 10 before breeding age is attained, the rat by eating young tuatara (or eggs) would effectively destroy a whole generation of the reptile.
Tuatara eat live prey, bird eggs, birds young and old, weta's, and in the pre-history of NZ Leiopelma frogs would likely to have been in the diet.

If the difference was found to be significant, this would indicate the sex of tuatara was determined not only by temperature during incubation, but also by genetics and the interplay between the two.
"A study of tuatara chromosomes published in the 1960s did not show obvious sex chromosomes, like X and Y that humans have, so it has been assumed their sex is not determined by genetics," he said.
Tuatara have no copulatory organs, so it usually takes up to eight years to determine their sex.

 Tuatara
Tuatara are the only living members of an ancient order of reptiles that evolved around 225 million years ago.
Tuatara have remained the same over 80 million years due to New Zealand’s isolation, and this may be the reason they still survive.
Adult tuatara are mainly nocturnal but the young come out during the day until they are about six months old, which reduces the chances of being eaten by an adult tuatara.
