Tiny Tuatara are looking Tip Top

Six juvenile Tuatara enjoyed the sun yesterday as Wellington Zoo keepers checked their condition before they enter brumation, similar to hibernation in mammals.

With winter signalling the end of the growing season, keepers take the opportunity to weigh and measure the two year old hatchlings, and will take measurements again in October.

“These biannual measurements allow us to assess their current condition, and also keep track of their growth over time,” explained Amanda Tiffin, Life Science Manager.

The data is collated by Barbara Blanchard, Captive Management Coordinator for Tuatara, who also works at the Zoo.

The juvenile group dig their own burrows, and their activity levels around this time of year mean that keepers don’t necessarily see each one daily. This biannual check gives them a great opportunity to do a thorough visual health check, which includes looking for any wounds or signs of shedding.

“The six Tuatara we checked look to be in good condition,” said Amanda Tiffin. “They enjoyed the chance to soak up some sun before digging back into their burrows for brumation.”

Brumation is a period of dormancy in reptiles, similar to hibernation. While mammals sleep through hibernation, reptiles become more lethargic. Their metabolism slows down, and while they will be offered food, they can make it through the whole winter without needing to eat. They will however seek out water.

“These Tuatara have beautiful markings, and are really cute!” said Amanda Tiffin. “It is a unique chance to see them all up close, and check their development.”

Visitors can see this national treasure up close at the Zoo daily during the Kiwi Talk at 1.15pm.
