Watch: Rare footage of ancient reptile hatching

Incredibly rare footage of a tuatara hatching from its egg has been caught on camera at Chester Zoo.

It is the first time the intricate process has ever been filmed in such stunning detail.

The tuatara is an ancient reptile that has lived on the planet for more than 225 million years – older than many species of dinosaur.Last year, reptile experts at Chester became the first in the world to successfully breed the rare animal outside the species’ native New Zealand.

Now, six more have hatched at the zoo and leading keepers to believe that they have found the ‘winning formula’ when it comes to breeding the mysterious creatures.

Only a handful of zoos worldwide work with the species and the new arrivals are a huge boost to the global population of the reptiles, which are notoriously hard to care for. The tuatara takes more than 20 years to reach sexual maturity and only reproduces every four years.

Isolde McGeorge, reptile keeper, said:

Tuatara are found wild only in New Zealand and are the last surviving species of its group, commonly known as beak heads, or Rhynchocephalia.

Around 70 million years ago the species became extinct in Europe, Asia, North and South America and Africa. To this day, conservationists aren’t sure how and why they were wiped out. Since then, tuatara have only survived in New Zealand, where the animal now has iconic status. It is steeped in Māori culture and is highly revered, with the islands on which they live now protected and which very few people are granted permission to visit.

Keepers at Chester Zoo have been caring for tuatara since 1962.

The ground-breaking footage was captured by cameras filming for series three of The Secret Life of the Zoo, which starts at 8pm on Tuesday 28 February on Channel 4.
