Life
The tuatara is a unique reptile, found only in New Zealand. This reptile is a member of the order Sphenodontia, which has over 250 million years of history.
While the other reptiles in the order have many species around the world, the tuatara has only two species.
These reptiles share many similarities with their fossil counterparts, such as a lizard-like skull and the distinct type of haemoglobin in their blood.
Although tuataras are not known to breed, the species is threatened by habitat loss and invasive species.
A recent genome sequence of the tuatara revealed that the animal’s genome contains several types of repetitive elements.
The majority of these repetitive sequences are transposable elements, accounting for 31% of the genome.
Segmental duplications comprise another 4% of the tuatara’s genome, but their high sequence identity suggests that they have recently evolved.
In addition, the tuatara genome is 2.4 times larger than the genome of anoles, which suggests that these duplications have occurred in the tuatara.
Conservationists have succeeded in eradicating the presence of rats and other pests on many smaller islands in New Zealand.
This has allowed the tuatara to breed and make a comeback. This work is ongoing, however, because many islands are still not open to the public and are subject to strict quarantine procedures.
If introduced rats are accidentally released, the effects could be disastrous. Therefore, the study of the tuatara on New Zealand’s islands is crucial in understanding the future of the species.
Habitat
The habitat of tuatara is changing. As the climate changes, this endangered species is becoming increasingly vulnerable.
Climate change has the potential to affect the tuatara habitat and even its sex ratio, meaning that it is increasingly important to restore the population in the south.
Scientists have started the project by collecting eggs from the wild. They are then incubated in a laboratory environment.
When they reach maturity, the young are released onto the offshore islands where they live in a protected environment. The hope is to restore the population to its natural habitat and to increase the species’ population size.
During the day, tuataras spend the majority of their time basking on vegetation.
They become more active at night and dig their own burrows, although they sometimes use fairy prion burrows as well.
These burrows are not only a place for tuatara to sleep, but also provide protection. While tuataras typically prey on non-flying insects and beetles, they are also capable of crushing larger prey.
New Zealand’s strict legal protections have helped protect tuatara populations. In 1895, the tuatara was granted CITES Appendix I classification, the most restricted.
While there are still poaching incidents in the area, the number of tuatara specimens has decreased.
This has reduced poaching significantly. Tuataras live in islands that have been carefully managed for many years.
Predators
Despite their small size, tuataras are highly active predators.
They hunt various species of invertebrates and dig burrows. Males have distinctive spines on their necks, which they use when attracting females and defending their territories.
Tuataras have a range of colors, from olive green to orange-red, and their coats are shed once a year. Their diets are varied and include seabird eggs and chicks.
After the rat population was destroyed, scientists monitored tuataras throughout the night. Spotlight searches were conducted on Taranga island before and after rat eradication.
The researchers concluded that rat eradication helped increase the number of tuataras, and the percentage of juveniles tended to increase.
However, these results are far from conclusive. It is still important to understand the role of predators in tuatara populations in order to protect the species from extinction.
The presence of tuataras on the island is related to their habitats. They can occupy many burrows in close proximity.
Individual tuataras use several burrows, and they may share a single one at different times. Males show a preference for certain burrows while juveniles tend to use many burrows at the same time.
During intense confrontations, tuataras may chase their prey, bite them or otherwise attack them. During these encounters, males make croaking sounds, which are a byproduct of chest compression.
Average Life Span
The average life span of Tuatara is sixty years, but the species can live much longer than that.
The Tuatara is considered one of the slowest-growing reptiles, with a growth rate of less than five percent.
They are slow-growing, reaching sexual maturity between 10 and 20 years. Their lifespan is sixty to one hundred years, but some specimens are said to be more than a hundred years old.
Tuataras are a single species, although the Brothers Island tuatara was originally considered a separate species.
All tuataras are members of the same genus, Sphenodon punctatus. The Tuatara’s biological characteristics are quite unique among other reptiles.
Their low basal metabolic rate, high energy demands, and slow reproduction rate make them exceptionally resistant to human-made threats.
The average Tuatara lifespan is sixty years, but it can range from one to a hundred years in captivity.
These creatures reach sexual maturity between ten and twenty years of age, and they continue to grow until they are 35 years old.
The Tuatara has a third eye, referred to as the parietal eye, located on its head. It is not a functional eye, but it does contain rod-like structures and a degenerated nerve connection to the brain.
The female Tuatara lays between six and ten eggs in a single clutch. Once laid, these eggs may take fifteen months to hatch. Tuataras have three rows of teeth, with the bottom row fitting between the two top rows.
Diet
The tuatara lives on foggy offshore islands where it lives in burrows with sea birds.
Its range extends up to five kilometers, with each burrow separated by two to three meters. The tuatara can regrow its tail, but it has no natural predators.
Its population has decreased dramatically in the past, mostly because of the introduction of predators. Tuataras are known to be slow-reproducing. In the wild, they can live 60 years.
In captivity, they can live up to one hundred years. Sexual maturity occurs between 10 to 20 years of age. During this time, they continue to grow until they reach maturity.
The tuatara’s diet is primarily composed of insects, lizards, and birds. They are also known to consume bird eggs and hatchlings.
Their digestive system is slow, and they breathe only once every seven seconds. Tuataras can be found in all parts of the world, and once roamed the mainland, the tuatara was a common sight.
Unfortunately, humans drove tuataras to extinction, erasing this unique species from the island.
In 1989, the tuatara was formally recognized as a separate species, but it was no longer included in the Southwater encyclopedia.
Until the end of 2009, tuataras were only listed as one species. The species of tuatara is currently classified into two subspecies, the Northern tuatara is the largest in New Zealand, while the Brothers Island tuatara is smaller.
Tuataras are olive green to slate gray in color, but their skin color changes throughout their lifetimes. Unlike humans, tuataras are sexually dimorphic, with a spine-like crest along their neck and back.
