Fossil Reveals Secrets of One of Nature’s Most Mysterious Reptiles 2022-03-06T05:00:00Z If you'd like to save a branch of the evolutionary tree, consider the Brothers Island tuatara, a small New Zealand reptile. With so many species being endangered, which one should I help? 2011-03-15T04:00:00Z Moreover, while the modern tuatara resembles its distant ancestors anatomically, life aboard a long-isolated land mass clearly has wrought major changes in the reptile’s physiology and behavior, pushing the tuatara to Guinness-worthy extremes. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z Finally, there is an ongoing debate about whether there are actually two subspecies of tuatara — crucial information for conservation strategies.

Behold, Newstralia 2010-04-09T16:54:00Z The tuatara of New Zealand, however, lays but ten—white hard-shelled, long and oval—at intervals between November and January. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 1 "Edwardes" to "Ehrenbreitstein" As a result, tuataras remain active at night, and in weather just a few degrees above freezing, said Dr. Daugherty, “at temperatures at which most reptiles couldn’t survive.” Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z The lack of current samples is not desirable for designing genetics-based conservation approaches, but, given the tuatara’s longevity, any recommendations arising from the study are still likely to be valid. Tuatara genome reveals diverse insights into a remarkable reptile 2020-08-04T04:00:00Z Like many reptile species, the gender of tuatara hatchlings is determined by the temperature of their eggs in the nest. 60 Rare Tuatara Reptiles Moved to Predator-Free New Zealand Island 2012-04-14T14:45:00.240Z It is probable that the very peculiar lizard-like reptile of New Zealand—the "tuatara" or Sphenodon—entered its area at a still earlier stage of surface change. More Science From an Easy Chair I have seen it standing out like a ball on the head of a dead crocodile, and in the living tuatara—the very primitive New Zealand lizard—it still has a retina and optic nerve. The Story of Evolution In every way, tuataras are late bloomers and passionate procrastinators. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z Without mammalian predation pressure, the tuatara life cycle became ever more protracted. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z The carnivorous reptile thrived, feasting on wetas, worms, nesting seabirds and the occasional baby tuatara, and the population climbed to densities far higher than would be seen for a calorically needier meat-eating mammal. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z By the 19th century almost no tuataras survived on the New Zealand mainland. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z Yet the animal that may well be New Zealand’s most bizarrely instructive species at first glance looks surprisingly humdrum: the tuatara. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z For all the nobility of the comparison, the tuatara’s stately pace is also its Achilles’ heel, he added. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z A reptile about 16 inches long with bumpy, khaki-colored skin and a lizardly profile, the tuatara could easily be mistaken for an iguana. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z The tuatara — whose name comes from the Maori language and means “peaks on the back” — is not an iguana, is not a lizard, is not like any other reptile alive today. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z Certain tuatara organs and traits also display the hallmarks of being, if not quite primitive, at least closer to evolutionary baseline than comparable structures in other animals. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z Some researchers are looking at tuataras for clues to how dental implants, which are inserted directly into the jaw, might be improved. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z A male tuatara manages as a male bird does, by pressing his cloacal opening against the female’s. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z The quick-changing sequences are limited to so-called neutral regions of the tuatara’s DNA, affecting filler codes, rather than the molecular blueprints for how to build a tuatara. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z Yes, tuataras are out and about, working the night shift, hunting down other New Zealand fauna similarly adapted for the cold. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z “Walking through the forest at night, you can hear the tuataras eating — crunch, crunch, crunch.” Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z Then the eggs incubate in the ground for yet another year before a brood of finger-size baby tuataras will finally hatch. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z The tuatara also has a unique approach to mastication. Basics: Reptile?s Pet-Store Looks Belie Its Triassic Appeal 2010-11-22T21:16:00Z “If these were plants, most lizards would be like weeds, and the tuatara like a sequoia,” said Dr. Daugherty.
