What is the tuatara?
The Tuatara is a hypercar unlike any other. It is the culmination of over a decade of research and development to produce a road legal, high performance vehicle capable of delivering an otherworldly driving experience.
Is tuatara still alive?
Tuatara, along with other now-extinct members of the order Sphenodontia, belong to the superorder Lepidosauria, the only surviving taxon within Lepidosauromorpha. Squamates and tuatara both show caudal autotomy (loss of the tail-tip when threatened), and have transverse cloacal slits.
Is the tuatara protected by law?
The tuatara ( Sphenodon punctatus) has been protected by law since 1895. A second species, the Brothers Island tuatara ( S. guntheri, Buller, 1877), was recognised in 1989, but since 2009 it has been reclassified as a subspecies ( S. p. guntheri ).
Do tuatara hibernate?
Hatchlings hide under logs and stones, and are diurnal, likely because adults are cannibalistic. Tuatara thrive in temperatures much lower than those tolerated by most reptiles, and hibernate during winter. They remain active at temperatures as low as 5 °C (41 °F), while temperatures over 28 °C (82 °F) are generally fatal.
What are some interesting facts about the tuatara?
Facts. Tuatara are New Zealand’s largest reptile. Adult males measure up to about: 0.5 metres in length, and; weigh up to 1.5 kg when fully grown. The male has a distinctive crest of spines running along the neck and down the back. He can erect these spines to attract females or when fighting with other males.
What is the scientific name of the tuatara?
Tuatara Facts At A Glance. Other Name(s): Beak-head, Cook Strait tuatara. Scientific name: Sphenodon punctatus. Type of Animal: Reptile. Animal Family: Sphenodontidae. Where Found: New Zealand. Average Length: 61 cm (24 in), male; 45 cm (18 in), female. Weight: Up to 1 kg (2.2 lb.), male; up to 0.5 kg (1.1 lb.), female.
What do tuataras eat?
Tuatara are nocturnal burrowing reptiles of coastal forests, where they forage over a restricted home range and feed on bird eggs, chicks, invertebrates, amphibians, and small reptiles. Since these reptiles are cold-blooded and live in a cool climate, tuataras have extremely low metabolic rates,...
Is a tuatara a reptile or amphibian?
The tuatara itself is one of the most primitive of all reptiles and is sometimes called a ‘living fossil’; an animal that has changed very little over a vast period of time. Both its brain and its gait (the way in which it walks) resemble that of an amphibian.
Are tuatara protected in New Zealand?
The tuatara was one of New Zealand’s first native species to be fully protected by law in 1895. Before then, hundreds of specimens were shipped overseas for museums and private collections. Poaching is still a problem, although diminished by the tuatara’s legal protection and remote locations.
Why is tuatara important to biologists?
Tuatara are therefore of huge international interest to biologists. They are recognised internationally and within New Zealand as species in need of active conservation management. The tuatara is a single species Sphenodon punctatus.
What is the main threat to the tuatara?
The main threat to the tuatara is non-native, introduced mammals (in particular rats). Together with captive breeding, the eradication of these species from the tuatara’s island homes has been the main focus of conservation programs.
Is the Brothers Island tuatara a second species?
A second species, the Brothers Island tuatara ( S. guntheri, Buller, 1877), was recognised in 1989, but since 2009 it has been reclassified as a subspecies ( S. p. guntheri ). Tuatara, like many of New Zealands native animals, are threatened by habitat loss and introduced predators, such as the Polynesian rat (Rattus exulans).
