A tuatara typically weighs between 200-1,000 grams, with males being larger and heavier than females.
The oldest known tuatara is estimated to be over 100 years old, with some individuals in the wild believed to live even longer. Tuataras are unique reptiles native to New Zealand and are known for their slow growth and long lifespan. Their longevity has made them a subject of interest for researchers studying aging and conservation.
Tuatara are ancient reptiles, endemic to New Zealand. Carnivorous creatures which feed on small mammals, birds, insects such as weta, frogs and other reptiles, they are equipped with very sharp teeth which they use to catch their prey. They simply draw close to these smaller creatures, and pounce quickly to catch them. The tuatara grip their prey with their two sets of upper teeth and one set of lower teeth which hold the prey firmly. These strong teeth are also used to break through egg shells to eat the chicks of the seabirds that share the tuatara's habitat.
A behavioral adaptation of the tuatara is its ability to remain inactive during the hottest parts of the day, seeking shelter in burrows or under rocks to avoid overheating. This thermoregulatory behavior helps the tuatara conserve energy and maintain optimal body temperature. Additionally, tuataras are primarily nocturnal, which allows them to hunt for insects and other small prey during cooler nighttime hours, further enhancing their survival in their native habitats.
Tuatara have two eyes, like most reptiles, but they also possess a unique third "parietal eye," located on the top of their head. This third eye is not used for seeing in the traditional sense but is thought to help regulate circadian rhythms and detect light. The parietal eye is covered by scales and is more of a sensory organ than a fully developed eye. Thus, while tuatara have two functional eyes, their third eye adds an interesting aspect to their anatomy.
Either of two nocturnal lizard-like reptiles (Sphenodon punctatus or S. guntheri) that are found only on certain islands off New Zealand and are the only extant members of the Rhynchocephalia, an order that flourished during the Mesozoic Era. Also called sphenodon.
There is no particular name for a baby tuatara. Newly hatched tuatara are called hatchlings, and tuatara that are not yet adult are simply called juvenile tuatara.
No. Iguanas and tuatara are quite different species. Whilst both iguanas and tuatara are reptiles, the iguana is a type of lizard, whereas the tuatara is not classified as a lizard.
The tuatara is a reptile.
There are only two species of tuatara: The Northern tuatara (Sphenodon guntheri) and the Brothers Island tuatara (Sphenodon punctatus).
No, Rhynchocephalia is not a subset of Mammalia. The tuatara is a reptile.
