What are the two species of tuatara?
There are two species of tuatara. One is the Brothers Island tuatara (Sphenodon guntheri, pictured), which, until recent re-introductions to sanctuaries, only survived on North Brother Island in Cook Strait. The other species is the common tuatara (Sphenodon punctatus), which survives on many other offshore islands.
Can you keep tuatara as pets?
In the illegal pet trade, a single tuatara can fetch more than $40,000. They resemble lizards, but actually belong to a distinct order (Sphenodontia), of which the two tuatara species are the only surviving members. Tuatara have an extremely slow growth rate.
How is a tuatara different from a lizard?
The name “tuatara” is a Maori word meaning “peaks on back” or “spiny back.” Tuataras have no external ears as lizards do; they enjoy cooler weather, while lizards like it warm; and, unlike lizards, tuataras are nocturnal. But their most curious body part is a “third eye” on the top of the head.
Why is a tuatara not a lizard?
Are tuatara cold blooded?
Tuatara have an interesting relationship with temperature. They are ectotherms (”cold blooded”) so their body temperature depends on the ambient temperature. They live in the forest, and are active at night, but spend sunny days basking at the entrance to their burrow.
What is unusual about the tuatara eyes?
The tuatara has a third eye on the top of its head called the parietal eye. This eye has a retina, lens, cornea, and nerve endings, but it is not used for vision. The parietal eye is only visible in hatchlings, as it becomes covered in scales and pigments after four to six months.
Why is a tuatara not considered a lizard?
What is the scientific name for the tuatara?
The tuatara’s scientific name is Sphenodon punctatus. “Sphenodon” originates from the Greek words “sphen,” meaning “wedge,” and “odon,” meaning “tooth.” “Punctatus” is a Latin word that means “pointed.” The word “tuatara” in the Maori language means “peaks on the back.” Maoris are New Zealand’s indigenous Polynesian people.
What kind of animals are on the tuatara Islands?
The most serious threat to wild tuataras are the mammalian predators that have been introduced to the islands via human settlement. Dogs and rats have had the most serious impact on tuatara populations, but other animals such as ferrets and cats have affected their numbers as well.
Is the tuatara the only lizard in New Zealand?
New Zealand’s endemic tuatara is a very unusual animal. They are the only living representative of a group of reptiles known as Rhynchocephalia (sometimes known in the past as Sphenodontia) that first appeared over 200 million years ago. They are not lizards!
What kind of habitat does a Tuatara live in?
Tuataras are solitary animals that live in burrows, but they have been known to share their burrows with certain seabirds that they live in harmony with. Both males and females have similar coloring. Most have skin that is a muted, olive green, or rusty brown color in order to help them blend into their surroundings.
