Two baby Madagascar Giant Day Geckos (Phelsuma grandis) hatched last month from eggs laid by adults currently living in the rainforest habitat at the Tennessee Aquarium.
In spite of their name, the babies are only a few inches long right now. The Aquarium's experts are caring for these tiny reptiles behind the scenes in a special Gecko nursery.
The Aquarium’s herpetology team says the pair are currently growing well and “eating like champs.”
The Madagascar Giant Day Gecko has a bright green body with brilliant red markings. The red markings fade as the Gecko ages, so the adults are mostly green in color. In the wild, these Geckos feed on insects, small reptiles, nectar and pollen. Adults can grow to around 12 inches in length.
Geckos are a type of Lizard. Madagascar Giant Day Geckos are native to the tropical forests of northern Madagascar, and a few other locations to which they have been introduced by humans.
Madagascar Giant Day Geckos are rumored to be the inspiration for the Geico Gecko of advertising fame.
Conservationists at Chester Zoo have celebrated an unprecedented number of births in 2018, including some of the world’s rarest and most at-risk species.
Adorable cub Kyra was the first Sun Bear to be born in the UK. Her birth was caught on the zoo’s CCTV cameras and people around the globe watched Kyra’s first moments with her mom. Kyra’s parents, Milli and Toni, were both rescued from poachers in Cambodia.
Conservationists estimate that less than 1,000 Sun Bears remain in the wild across Southeast Asia. Deforestation and commercial hunting for their body parts have decimated their numbers.
Critically endangered Western Chimpanzee Stevie was the first of her kind to be born at Chester Zoo in nearly 10 years.
Stevie’s birth followed a scientific project, spanning several years, which carefully assessed the genetics of all Chimpanzees in zoos across Europe. The study confirmed that the troop of Chimps at Chester Zoo is the highly-threatened West African subspecies – one of the rarest in the world – establishing them as a critically important breeding population. It is estimated that as few as 18,000 West African Chimpanzees now remain in the wild.
After an unusually long pregnancy believed to have lasted 25 months, Asian Elephant Thi Hi Way gave birth to a healthy male calf, who keepers named Anjan.
A major Chester Zoo project in Assam, northern India, has successfully found ways to eliminate conflict between local communities and the nearby Asian Elephant population, offering a blueprint for the future conservation of the species.
Greater One-horned Rhino
The momentous birth of Greater One-horned Rhino calf Akeno, born to mom Asha, was captured on CCTV cameras at the zoo.
Keepers watched as Asha delivered her calf safely onto to soft bedding after a 16-month-long gestation and 20-minute labor.
At one stage, the Greater One-horned Rhino was hunted almost to extinction and less than 200 survived in the wild. Thankfully, steps to protect the Rhinos were taken just in time and today there are around 3,500 in India and Nepal.
A rare Okapi calf named Semuliki arrived to first-time parents K’tusha and Stomp. The Okapi is found only deep in the forests of the Democratic Republic of Congo and its highly secretive nature contributed to it being completely unknown to science until 1901.
Despite being a national symbol and protected under Congolese law, Okapi populations declined in the wild by nearly 50% over the past two decades and the species is now listed as endangered by the International Union for the Conservation of Nature (IUCN).
A clutch of rare baby Bell’s Anglehead Lizards – also known as Borneo Forest Dragons – hatched at the zoo, helping conservationists uncover more about the species’ breeding patterns, life cycle and habits.
The Lizards’ wild south Asian habitat however, is being decimated to make way for unsustainable palm oil plantations – a threat which is pushing many species in the region to the very edge of existence.
The birth of a tiny Silvery Gibbon astonished visitors to the zoo who were able to admire the infant just minutes after its birth.
Conservationists hailed the arrival of this highly endangered primate, with just 4,000 of its kind now remaining on the island of Java, Indonesia, where the species is now listed as endangered by the IUCN.
Keepers were tickled pink by the arrival of 21 Flamingo chicks. Each of the fluffy newcomers was carefully hand fed by the zoo’s bird experts four times a day for five weeks until they were developed enough to fully feed for themselves.
Flamingo chicks are white or grey in color when they first hatch, resembling little balls of cotton wool, and begin to develop their famous pink plumage at around six months old.
The first set of Babirusa triplets were born at the zoo, a huge boost to the species which has experienced a recent population crash on the island of Sulawesi, Indonesia.
Once considered fairly common, the rapid decline comes as result of hunting for their meat and habitat loss, which has seen Babirusas disappear from many parts of the island.
Eastern Black Rhino
The arrival of Jumaane, a rare Eastern Black Rhino calf, left a handful of lucky zoo visitors in shock as his birth took place right in front of them.
Conservationists now estimate that fewer than 650 Eastern Black Rhino remain across Africa – a staggeringly low number driven by an increase in poaching to meet demand for rhino horn, which supplies the traditional Asian medicine market.
The birth of Jumaane is another vital boost to the Europe-wide breeding program which is crucial for the conservation of this critically endangered species.
Five Henkel’s Leaf-tailed Geckos (Uroplatus henkeli) have arrived at Lincoln Park Zoo – the first-ever successful hatch at the zoo for this rare Lizard species. The hatchlings will be on exhibit at Regenstein Small Mammal-Reptile House in the coming weeks.
The zoo’s Henkel’s Leaf-tailed Geckos were given a breeding recommendation from the Leaf-tailed Gecko Species Survival Plan® (SSP), which manages the species’ population throughout zoos accredited by the The Association of Zoos and Aquariums (AZA). The SSP recommendations – which determine the exact individuals that should breed with each other – are made using demographic and genetic analyses conducted by population biologists at the AZA Population Management Center, which is based at Lincoln Park Zoo.
Henkel's Leaf-tailed Geckos are named for their distinctive namesake tail. That remarkable appendage and their rough brown and green skin helps these Lizards camouflage themselves against tree bark with uncanny ease.
Tiny pads on the feet of Henkel's Leaf-tailed Geckos produce a strong adhesive effect, enabling them to climb and cling to a variety of surfaces. In the wild, these Lizards spend most of their time in the treetops, feeding on insects. They descend to the ground only when laying eggs in leaf litter on the forest floor.
Although adults can grow to 11 inches long, hatchlings are much tinier, as you can see in the photos. The newcomers are welcome arrivals for a species that is classified as Vulnerable by the International Union for Conservation of Nature (IUCN).
These Lizards are found only in Madagascar, where they face threats from logging operations and from deforestation as people burn the forest to make small farms. They are also collected illegally to supply the pet trade and are routinely taken from protected areas within Madagascar.

The population of critically endangered Jamaican Iguanas is on the rise, thanks in part to the efforts of researchers at the San Diego Zoo Institute for Conservation Research’s Kenneth and Anne Griffin Reptile Conservation Center (an off-exhibit breeding facility at the San Diego Zoo Safari Park).
Since September, four Jamaican Iguanas have hatched here from eggs of two different pairs of adult Iguanas. One egg from the first clutch hatched September 4, and three eggs from the second clutch hatched October 6, 7 and 11. With the addition of these four new animals, a total of 11 Jamaican Iguanas now reside at the Park’s Reptile Conservation Center.
The baby Iguanas now have a much lighter gray color overall, with more pronounced striping than they will have when they become adults. As they grow, their body will become dark gray and rust-colored, with greenish-blue highlights. Jamaican Iguanas continue to grow over their entire lifetime, and they can eventually reach up to three feet in length and weigh up to 15 pounds.
San Diego Zoo Global first received a group of Jamaican Iguanas in 1996: three males and three females. The first successful hatching of this critically endangered lizard occurred in 2013, with the birth of a female that still lives at the Reptile Conservation Center. She will become part of the center’s breeding program when a suitable mate can be found for her.
"I'm very pleased with the results of our work this year,” said Jeff Lemm, conservation program specialist at the San Diego Zoo Institute for Conservation Research. “Our job is to help make the animals successful at reproducing through the husbandry we provide, and it's fantastic that we are starting to achieve these goals."
The Jamaican Iguana (Cyclura collei) is found only in the tropical dry forests of the Hellshire Hills outside of Kingston, Jamaica. They are Jamaica’s largest native species and believed to be extinct in the 1940s. However, in 1990, a pig hunter’s dog found a live specimen and the Iguana was brought to the Hope Zoo in Kingston, Jamaica. That same year, a survey of the Hellshire Hills found a small population of fewer than 100, and researchers began a large-scale program to try to save this Iguana from extinction. Due to deforestation and threats from non-native animals (including mongooses, cats, dogs and pigs), the Jamaican Iguana is currently listed as “Critically Endangered” on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species.
Three colorful Chameleons, so tiny they each fit on the end of a finger, have hatched at Chester Zoo.
This is the first time the zoo has successfully bred the species, known as Cameroon Two-horned Mountain Chameleons. The first in a clutch of three eggs, laid by a female named Ruby, hatched in late August with two more following soon after.
Lead Herpetology Keeper Adam Bland said, “These Chameleons have a really unusual appearance. They’re sometimes referred to as the Cameroon Sailfin, owing to a sail-like flap of skin running along their backs. The males of the species boast two large horns just above their upper jaw which they use for jousting with other males.”
“Even as babies they have their iconic large eyes which, at their current size, may appear a little too big for their body. However these give them 360° arc vision so they can see in two different directions at once and look out for predators,” added Bland.
As the name suggests, the Cameroon Two-horned Mountain Chameleons live at altitude in the West African nation of Cameroon. These lizards are usually green in color, but males turn blue when trying to attract a mate.
Dr Gerardo Garcia, Curator of Lower Vertebrates and Invertebrates at the zoo, added, “These Chameleons are thought to live in just 10 locations in the highlands of Cameroon as they only thrive at a very particular altitude (between 700m and 1,900m), in very specific forest habitat. As much of the highlands of Cameroon comprise of savannah and grasslands, it really restricts their range. Sadly, with that already small amount of available habitat being affected by human activity - degradation, agriculture and climate change - it’s making these Chameleons more and more vulnerable.
“Another big threat to their survival is the international pet trade. Thousands of live Chameleons have been taken from the wild and traded from Cameroon in the last dozen years,” Garcia added. The species is listed as Near Threatened on the IUCN Red List.

Tulsa Zoo’s Reptile and Aquatics department recently announced the hatching of six Desert Iguanas. The little lizards are currently on display in the Zoo’s Conservation Center reptile nursery.
The Desert Iguana (Dipsosaurus dorsalis) is one of the most common lizards. It is native to the Sonoran and Mojave deserts of the southwestern United States and northwestern Mexico. They are also found on several Gulf of California islands.
The Desert Iguana is a blunt, medium-sized lizard that grows to a maximum size of about 61 cm (24 in), including the tail. They are grayish tan to cream in color, with a light brown reticulated pattern on their backs and sides. The belly is pale. During the breeding season, the sides become pinkish in both sexes.
Their preferred habitat is largely contained within creosote bushes on mainly dry, sandy desert scrubland below 1,000 m (3,300 ft). They can also be found in rocky streambeds. In the southern portion of its range, this lizard lives in areas of arid subtropical scrub and tropical deciduous forest.
The Desert Iguana can withstand high temperatures and are out and about after other lizards have retreated into their burrows. If threatened, they will scamper into a shrub and go quickly down a burrow. Burrows are usually dug in the sand under bushes like the creosote. They are also known to use burrows of kit foxes and desert tortoises.
Mating takes place in the early spring. One clutch of eggs is laid each year, and each clutch will have three to eight eggs.
Desert Iguanas are primarily herbivorous, eating buds, fruits and leaves of many annual and perennial plants.
Birds of prey, foxes, rats, long-tailed weasels, some snakes, and humans are all known predators of this lizard and their eggs. The Desert Iguana is currently classified as "Least Concern" on the IUCN Red List of Threatened Species.
Cotswold Wildlife Park has become the first zoological collection in the UK to breed the rare Chinese Crocodile Lizard.
The sex of the newborn is currently unknown, and the baby Lizard is currently off-show in the specialist Reptile rearing room. However, visitors to Cotswold can see the adults in their enclosure in the Reptile House. In the future, the newest Lizard will go on to be part of a breeding programme for this rare species.
The Chinese Crocodile Lizard (Shinisaurus crocodilurus) is semiaquatic and found only in the cool forests of the Hunan, Guangxi and Guizhou Provinces of southern China, and the Quảng Ninh Province in northern Vietnam. Very little is known about this rare species. It was first collected in 1928, and it remains the most recently named Lizard genus.
The species is viviparous, meaning it gives birth to live young. It has a gestation period of approximately nine months and litters consist of between 1-12 young.
In the wild, it frequently spends hours, motionless, perched on rocks or branches above slow-moving streams and ponds.
Due to habit destruction, illegal poaching, capture for the pet trade, and local consumption, population numbers of this Lizard are under serious threat. Unfortunately, this species is still widely used in traditional Chinese medicine. The Lizard’s ability to remain immobile for hours, occasionally days, led to the belief that it could cure insomnia. In China they are also known as “the sleeping serpent”.
Thirteen proved to be a lucky number for one of the planet’s rarest reptile species! Zoo Atlanta has had their most successful season ever for hatching Guatemalan Beaded Lizards. The Zoo welcomed a total of 13 hatchlings this spring, which is a record for Zoo Atlanta.
Zoo Atlanta is one of only four zoos in the U.S. housing Guatemalan Beaded Lizards. Since the arrival of the Zoo’s first hatchling in 2012, a total of 35 have successfully hatched in subsequent years.
Guatemalan Beaded Lizards lay their eggs in fall and early winter. The 13 new hatchlings began emerging from their eggs on March 31, 2017.
“Every animal birth at Zoo Atlanta is important, but it is especially so when we consider that there are so few Guatemalan Beaded Lizards in the wild. This species is not only exceptionally rare but challenging to reproduce,” said Hayley Murphy, DVM, Vice President of Animal Divisions. “We are very proud to see Zoo Atlanta leading the way in helping to ensure a future for this species and in sharing what we have learned with our partners in the U.S. and Guatemala.”
The Guatemalan Beaded Lizard (Heloderma charlesborgeti) is an example of an animal most Americans would have no awareness of were it not for zoological populations.
As reclusive as they are rare, the lizards are found only in the Motagua Valley in Guatemala, where they are believed to number fewer than 200 in the wild. The species and its close relatives, which include the Gila Monster of the southwestern United States, are the only known venomous lizards.
The Beaded Lizard is a specialized vertebrate nest predator, feeding primarily on bird and reptile eggs. It is semi-arboreal and can be found climbing deciduous trees in search of prey when encountered above ground. It occasionally preys upon small birds, mammals, frogs, lizards, and insects.
The lizard species becomes sexually mature at six to eight years and mates between September and October. The female will lay her clutch of two to 30 eggs between October and December, and the clutch will hatch the following June or July.
Young lizards are seldom seen, emerging from underground at two to three years of age after gaining considerable size.
Although Guatemalan Beaded Lizards spend most of their lives below ground and rarely encounter humans, wild populations face serious challenges because of habitat loss and illegal trade. The species faces additional pressures from fear-based killing resulting from long-held myths that the lizards have supernatural powers.
Zoo Atlanta has worked with the Foundation for the Endangered Species of Guatemala on Conservation Heloderma, which works to purchase and protect Guatemalan Beaded Lizard habitat; combat black-market trade; promote local education; and improve the lives of people living in communities that share the lizards’ native range.
The properties of the Guatemalan Beaded Lizard’s venom, which is used only in self-defense and is not used to capture prey, have only recently become known to science. Unlike most lizard species, the Guatemalan Beaded Lizard has a high aerobic capacity and is able to stabilize its blood sugar levels during contrasting periods of eating and fasting, thanks to a unique hormone. This hormone has been synthesized by pharmaceutical companies in the treatment of human diabetes.

The Alice Springs Desert Park, in the Northern Territory, Australia, has successfully produced fourteen new resident Thorny Devil Lizards.
The recent hatching of the fourteen healthy Thorny Devils (Moloch horridus), also known as Thorny Dragon, adds to the Desert Park’s diverse range of wildlife currently available for viewing.
Specialist Keeper, Invertebrates and Reptiles, Pete Nunn said that the Desert Park is thrilled to have such an extensive collection of Thorny Devils in captivity. “Thorny Devils are not normally kept, let alone bred at most zoos and wildlife parks around Australia,” he said. “The Thorny Devil usually lives in the arid scrub land and desert that covers most of Central Australia. For example, it inhabits the Tanami and Simpson Desert in the deep interior.”
Over time the Thorny Devils have evolved and adapted to the environment they live in.
“Thorny Devils live on a diet of nothing but small black ants. They feed in the cooler mornings and late afternoon,” Mr. Nunn continued. “When they locate a trail of ants they lick them up with their short, sticky tongue. Thorny Devils might eat a thousand or more ants in a single meal.”
When it comes to hydration, Thorny Devils collect moisture in the dry desert by the condensation of dew on their bodies at night.
“This dew forms on its skin, and then it is channeled to its mouth in microscopic grooves between its spines,” said Mr. Nunn.
The hatchlings took 98 days to incubate and weighed in at a tiny two grams.
From the fourteen total Thorny Devils that hatched, four are on display at the Alice Springs Desert Park’s nocturnal house, sand country exhibit.
