What is a tuataras worst nightmare?

The worst nightmare of the tuataras would be either consider themselves lucky/unlucky to have survived as the only species left in earth in order Ryncocephalia of class Reptilia or to have strucked to the country Newzeland at the time of separation of the continents due to plate tectonics.

Why is a tuatara in danger?

Tuataras live in small caves on islands near New Zealand. During the days of sailing ships, rats lived aboard sailing ships. The rats escaped from some of those ships and landed on some of those islands. They ate the tuataras on those islands. That reduced the number of islands with tuataras.

Where does the tuatara live?

Tuatara, ancient reptiles which are believed to be virtually unchanged since the time of dinosaurs, are native to New Zealand, the country in the southwestern Pacific Ocean. Although once plentiful throughout New Zealand, they are now restricted to around thirty offshore islands where they are protected from predators such as cats and rats.

Tuatara prefer to live in broad-leafed forest land and grasslands near seabird colonies, where the birds have dug burrows.

What is the tuatara's natural habitat?

From what I know, tuataras live on islands to protect them from predetors like rats, cats etc. They are found in the native bush (therefore there are lots of trees and shrubs). They sometimes share burrows with birds and other animals. They are cold blooded so they don't mind the cold, but like to bath in warm places. Hope it helps, Dio girl.

Are tuataras endangered?

Yes. Although tuatara numbers on outlying islands of New Zealand are quite healthy, the reptile remains on the endangered species list.

The main reason why the tuatara is endangered is the threat caused by introduced predators. The kiore (Polynesian rat) is responsible for the decreasing tuatara population, as are the two species of rats introduced by Europeans, while cats, dogs, stoats and ferrets have also contributed to the tuatara's decline.

On the mainland, deforestation has resulted in habitat loss, which has meant less food and safe shelter for the tuatara.

The tuatara's own breeding cycle and slow growth rate makes this reptile one of its own worst enemies. Tuatara only breed every second year and they are long-lived, meant they do not begin reproducing until they are 15-18 years old. They cannot reproduce quickly enough to compensate for their numbers being reduced by predators.

Why do tuatara only live in New Zealand?

Tuatara are native only to New Zealand, though there may be a few specimens in overseas zoos. They are nocturnal and slow moving.

A friend of mine inspecting one in a glass case in an UK museum, was most impressed as to the realistic presentation they had achieved, and having not seen one in NZ, spent some minutes examining the specimen. Then it blinked!

They are relatives of the dinosaur era, and have an ancestry of about 250 million years.

They are Sphenodontia, the 'dontia' part referring to a special tooth that is used in chipping open the shell. They reach sexual maturity in about 15 years, and may live to 100 years.

Where do tuatara live in New Zealand?

Tuatara live in their natural refuges of Stephens Island and Brothers Islands in Cook Strait. Some have been transferred to the Coromandel, and Little Barrier.

But the Little Barrier population were threatened by kiore, the native rat, and a small breeding population was rescued and established on Hen island.

How did tuatara come to new zealand?

The ancestors of the Tuatara originated about 200 million years ago, as a sub-species of the broad dinosaur family, and probably arrived via land bridges which are long gone. The route is probably that used by other NZ fauna, such as Kiwi.

Do tuataras have a third eye?

The tuatara of New Zealand has three eyes but they do not all have vision capabilities. The third eye is called the parietal eye. Although it has a lens, retina and nerve connection, it is not functional as an eye. it grows on top of the reptile's head, under the skin, and is not visible. Scientists have not been able to determine the function of this third eye, but it is thought that light falling on this third eye may influence certain biological functions such as sleep and hibernation.

What do tuatara eat?

Tuatara (Sphenodon punctatus) are reptiles that look like lizards but, often called living fossils, they are actually a different type of reptile that dates back to prehistoric periods over 200 million years ago. They eat insects like crickets, moths, beetles, and grasshoppers that they catch using their sticky fat tongues, and their diet also consists of other invertebrates like worms and snails. Additional foods in the Tuatara's diet are lizards, eggs, baby birds and smaller tuatara. They hatch from leathery-skinned eggs, and can grow to around 2 - 3 feet long (80 cm). The larger ones sometimes eat larger seabirds like petrels.

These nocturnal reptiles live on the islands off New Zealand, in burrows that they may dig themselves, but often take over from the burrowing petrels. They can have a lifespan as long as 60 years, and don't reach maturity until around 20 years old. Their numbers are reducing, and they are now considered vulnerable on the endangered species lists. They are preyed upon by rodents, pigs, and wild cats.

One of their most unique characteristics, besides their unique double row of teeth in the upper jaw, is their "third eye" called a pineal or parietal eye on top of their heads. Although this "eye" has a small lens and retina and is photoreceptive, it uses a different biochemical method of detecting light than normal vertebrates' rod cells or cone cells. The function is unknown and is under research. Tuatara have no external ears but are able to hear, and they retain some unusual features in their skeletons that may be evolutionary "left-overs" from fish.
the tuatra eats insects and birds.
The Tuatara's prey includes; beetles, crickets, and spiders. Their diet also consists of frogs, lizards, bird's eggs and chicks.

What is the relative of the tuatara?

The tuatara no longer has any close relatives. The once diverse order sphenodontia, (wedge-teeth) are now extinct with the exception of two species of Sphenodon remaining in New Zealand. Their 'closest' relatives are the other members of the superorder lepidosauria -- the lizards and snakes. It is worth mentioning, however, that this is not a very close relationship: tuataras and skinks are no more closely related than tree-shrews and humans.
