    Tuatara: Reproduction
    Jan 8 2026
    Summary: Join Kiersten as she takes you on a slow look at tuatara reproduction. For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean Show Notes: “Novel mating behaviors in male tuatara (Sphenodon punctatus) expand our understanding of reptile courtship,” by Sarah K. Lamar, Diane K. Ormsby, and Nicola J. Nelson. Austral Ecology, vol 49, Issue 2. https://doi.org/10.1111/aec13496 “Tuatara.” San Diego Zoo Wildlife Alliance, https://animals.sandiegozoo.org Music written and performed by Katherine Camp Transcript (Piano music plays) Kiersten - This is Ten Things I Like About…a ten minute, ten episode podcast about unknown or misunderstood wildlife. (Piano music stops) Kiersten - Welcome to Ten Things I Like About… This is a podcast about misunderstood or unknown creatures in nature. Some we’ll find right out side our doors and some are continents away but all are fascinating. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. Welcome back to Ten Things I Like About after a year end break. I hope the new year treats you well and opportunities abound. Let’s get started! We will continue with Tuatara. The third thing I like about tuatara is reproduction. As we travel along with the journey of discovery with tuatara, I want to pose a question to you. Is the tuatara a lizard? Or is it something else? Based on the physical description I outlined in the first episode, they seem to be lizards, if not very lizard like. But I want you to keep this question in the back of your mind as we progress through each new episode. We will revisit this question at the end of this series and see what we all think. Okay, let’s talk about how baby tuatara are made. Tuatara mating and reproduction is not like anything else in the reptile world. Long incubation periods, extensive maturation, and unusual consummation marks the reproductive cycle of the tuatara. It all begins sometime between January and March when males begin showing off to attract a mate. Remember those spines that they have on their neck and back, well they are there for pretties. They can fan out and shake the larger crest of spines in hopes of attracting a lady. For a long time we thought this was all the males did during the breeding season, but a study that looked more closely at males on Takapourewa Island revealed many more tricks they use to catch the ladies eye. Boys will come a courting at a female’s burrow and it can get complicated and lengthy. It might be a good idea that she gets to stay at home once all the excitement begins. First, the male adopts body positions that make him look big, such as inflating the body and gular region (that’s the chin area), elevating his body off the forest floor (the up part of a push-up), and erecting those spines on his neck and back. Next, the male will begin the slow proud walk, also known as stolzer Gang, in a circle around the female. He’ll perform this slow exaggerated walk in concentric circles, pausing occasionally, and decreasing the circle circumference with each pass. If the female is interested, she will leave her burrow entrance, allow the male to paw at her, and then mount her from behind. If there are obstacles in the male’s circular path, they will climb over, or go around. If the obstacle is too big to conquer, they’ll just shorten the circle to a semi-circle. I mean you gotta give them props for not getting distracted from their goal. The proud walk can last up to 44 minutes. A few novel behaviors were observed by researchers studying the Takapourewa population. Mirrored head bobbing between the male and female was observed a few times, something that has not been seen in reptiles before. The male would bob his head a specific number of times and when he paused, the female would bob the small numbers of times. This was a very exciting discovery that will need more research to determine what it means and if it is found in other populations of tuatara, but how very interesting. Vocalizations in tuatara are typically limited to croaks emitted when handled, or during aggressive moments between males, but these researchers encountered several males that purred during the mating process. We aren’t sure what this means or if this is a wide spread behavior but it is another exciting discovery. Once the female has accepted the male and he mounts her from behind, he positions his pelvis so that both of their cloacas come in contact. This is how he spreads his sperm to her. Males do not have special reproductive organs like most other reptiles. So they perform the cloacal kiss to pass their sperm to the female. Male sperm are fast swimmers. They are actually the fastest sperm in the reptile kingdom, moving two to four times faster than any other reptile’s sperm. The female can store the ...

    Tuatara: Where They Live
    Dec 17 2025
    Summary: Where do tuatara live? Can I see one in MY backyard? Join Kiersten to find out if you can see a tuatara in your own backyard. For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean Show Notes: “Distribution of tuatara”, Te Ara: https://teara.govt.nz/en/map “Tuatara” by Marc E. H. Jones and Allison Cree. Current Biology, Vol 22, Issue 23, PR986-R987, Dec 4, 2012. DOI: 10.1016/j.cub.2012.10.049, https://www.cell.com/current-biology “Sphenodon punctatus (Tuatara)” Animal Diversity Web: https://www.animaldiversity.org Music written and performed by Katherine Camp Transcript (Piano music plays) Kiersten - This is Ten Things I Like About…a ten minute, ten episode podcast about unknown or misunderstood wildlife. (Piano music stops) Kiersten - Welcome to Ten Things I Like About… I’m Kiersten, your host, and this is a podcast about misunderstood or unknown creatures in nature. Some we’ll find right out side our doors and some are continents away but all are fascinating. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. Last week’s overview of the tuatara probably made you want them in YOUR backyard, but they are only found in a small section of the world. This week we are going to find out where the tuatara live. The second thing I like about the tuatara is where they are found. To see a tuatara in the wild you will have to visit New Zealand. They are found on different islands surrounding the main island of New Zealand as well as on the mainland. Those found on the mainland are there due to a reintroduction program begun in 2005. The islands where you can find tuatara are fairly inaccessible which probably helped save them from extinction. The ones on the mainland were extinct before Europeans ever came to the island. There are about thirty islands surrounding New Zealand where you can find tuatara today. Those island include Poor Knights Island, Hen and Chickens Island, Little Barrier Island, Cuveir Island, Mercury Island, The Alderman Island, Karewa Island, Plate Island, Moutoki Island, Moutohora Island, and Tiritiri Matangi Island. These are all off the northern coast. Sphenodon punctatus occurs naturally on all of these islands except Moutohora and Tiritiri Matangi Islands where the Northern Tuatara were introduced to help increase their population. Tuatara can also be found on Stephens or Takapourewa Island, Trio Island, Titi Island, The Brothers Island, and Matiu or Somes Island. Sphenodon guntheri occurs naturally on The Brothers Island and was introduced to Titi and Matiu Islands to boost their population. Please excuse any mispronunciations. A scientific paper published in December of 2012 states that “there are about 32 natural populations of tuatara living on small offshore islands, a few island reintroductions, and at least one reintroduced mainland colony on the North Island [of New Zealand]. Most of the populations include just tens or hundreds of animals, but there are estimated to be at least 30,000 on Takapourewa Island.” End quote. The habitat that tuatara live in is an odd choice for a reptile as the islands are riddled with cliffs and exposed to strong winds. The vegetation is salt and wind tolerant; therefore, are pretty tough plants. The average temperature is below what the typical reptile can tolerate but tuatara are adapted to survive temperatures as low as 45 degrees Fahrenheit. They spend their days in burrows that are dug by seabirds such as petrels, prions, and shearwaters when they are available or they will dig their own burrows. They also spend time soaking up the sun on the cliffs. Tuatara are more active at night leaving their burrows or basking spots to hunt for food. This episode is a bit shorter than my usual episodes and I do apologize. I will make it up to you in future episodes of the tuatara. Thank you for visiting with me to find out where the tuatara lives. It is my second favorite about this seriously cool animal. As the holiday season is upon us, I will be taking a break until the new year. We will pick up where we left off with the tuatara in January 2026. If you're enjoying this podcast please recommend me to friends and family and take a moment to give me a rating on whatever platform your listening. It will help me reach more listeners and give the animals I talk about an even better chance at change. Join me in January 2026 for another exciting episode about the tuatara.

    Tuatara
    Dec 10 2025
    Summary: Tua-what? Join Kiersten to find out what the tuatara is. For my hearing impaired followers, a complete transcript of this podcast follows the show notes on Podbean Show Notes: “Sphenodon punctatus (Tuatara)” Animal Diversity Web: https://www.animaldiversity.org Music written and performed by Katherine Camp Transcript (Piano music plays) Kiersten - Welcome to Ten Things I Like About… This is a podcast about misunderstood or unknown creatures in nature. Some we’ll find right out side our doors and some are continents away but all are fascinating. My name is Kiersten and I have a Master’s Degree in Animal Behavior and did my thesis on the breeding behavior of the Tri-colored bat. I was a zookeeper for many years and have worked with all sorts of animals from Aba Aba fish to tigers to ravens to domesticated dogs and so many more in between. Many of those years were spent in education programs and the most important lesson I learned was that the more information someone has about a particular animal the less they fear them. The less they fear them the more they crave information about them and before you know it you’ve become an advocate for that misunderstood animal. This podcast will focus ten, ten minute episodes on different animals and their amazing characteristics. Please join me on this extraordinary journey, you won’t regret it. The next unknown animal I have chosen takes us on a journey through ancient times. We haven’t ventured this far back in time since we talked about the coelacanth. Welcome to the first episode of tuatara. The first thing I like about this unknown animal is their continued existence. You may be saying tau-what? Tuatara is our next animal. Let’s jump right into the classification which will answer some of your initial questions. Like what the heck is a tuatara? Remember classification is the way scientists identify different living things including animals and plants so that we all know who exactly we are talking about. The classification of the tuatara is as follows: Kingdom: Animalia (that’s the animals) Phylum: Chordata (chordates) Subphylum Vertebrata (that’s the animals that have an internal skeleton or the vertebrates) Class: Reptilia (that’s the reptiles) Okay! Now we’re getting somewhere. Tuatara must be a reptile! Order: Rhynchocephalia (there is only one reptile in this order) You guessed it! The tuatara. Family: Sphenodontidae Genus: Sphenodon Species: punctatus The scientific name for the tuatara is Sphenodon punctatus. There are two recognized species of tuatara. The Brother’s Island Tuatara is Sphendon guntheri. The first tuatara, Sphenodon punctatus, is referred to as the Northern tuatara. Now, we know this animal is a reptile, but what does it look like? Is it small? Is it large? Is it green, brown, or purple? Tuatara can be green, olive, or brick red in color. Their adult size ranges from 15 inches, or 40 cm, in the female to 24 inches, or 60cm, in the male. Both male and female have two crests of dull-edged spikes that travel down the back of the head to the neck with the second on the middle of the back along the spine. The male’s crests will be larger than the female’s which helps to distinguish the sexes from each other. They have four short legs and a long tail that usually exceeds the length of their body. They look a lot like a lizard, but they aren’t exactly lizards. We will dissect that statement in a future episode. They have no external earhole but they do have ears. They have two eyes that can focus independently and are placed on the sides of the head. They have a variety of scale structures along their body giving them a dinosaur-ish look. There are a few attributes that set tuatara apart from other species of reptiles. One of those is their third eye. Yes, they have a third eye, a parietal eye, right in the middle of the top of their head. It has a retina and is functionally similar to a normal eye. In juveniles it is exposed but as it ages a scale grows over it. We are currently uncertain of its purpose. Another attribute that sets the tuatara apart is their teeth. Tuatara teeth are fused to the jaw bone, unlike any other toothed reptile. This is an acrodont tooth structure. This speaks to the age of this species of reptile. The tuatara is the only living specimen of Rhynchocephalia. All of them, expect the tuatara, went extinct in the late Cretaceous period. We will dive into this topic in a future episode. One last thing about the tuatara before we end the first episode of this new series. One tuatara, many tuatara. When talking about the tuatara, the singular is the same as the plural. Thank you for choosing to start this series with me. We are going to have a fun time with the tuatara. My first favorite thing about them is them!
