The Fijian crested iguana is a unique and fascinating species. They're found on three Fijian islands, with Yadua Taba being their primary habitat.

These iguanas are quite small, with a head and body length of around 25cm, plus a 50cm tail. They're arboreal and herbivorous, which means they spend most of their time in trees and eat leaves, buds, flowers, and fruit from various forest plants.

Their diet consists of important tree species like Cevua, Kau Loa, and Vau, as well as some introduced species like passion fruit and the vine Gasau cebucebu, when they're found in disturbed areas.

The name Brachylophus is derived from Greek words, with "brachys" meaning "short" and "lophos" meaning "crest" or "plume", which refers to the short spiny crests along the back of this species.

The specific name, vitiensis, comes from the Fijian word for Fiji, and is a Latin toponymic adjective.

The Brachylophus genus is closely related to the Lau banded iguana and the Fiji banded iguana, both of which are part of the same genus.

These southwest Pacific iguanas, including Brachylophus, are thought to have descended from ancestral iguanas that rafted 9,000 km west across the Pacific Ocean from the Americas.

The Fijian crested iguana is a remarkable creature, with its closest relatives found thousands of kilometers away in the Americas.

These iguanas are arboreal and herbivorous, which means they spend most of their time in trees and eat leaves, buds, flowers, and fruit from various forest plants.

Their diet consists of native tree species like Cevua, Kau Loa, and Vau, as well as introduced species like passion fruit and the vine Gasau cebucebu.

The Fijian crested iguana has a distinctive appearance, with a head and body length of around 25cm, plus a 50cm tail.

They are primarily found on three Fijian islands, but are most commonly spotted on Yadua Taba.

Habitat loss, invasive predators, weeds, and climate change are the primary threats to the survival of these incredible creatures.

The Fiji crested iguana is a large and stocky lizard. It grows to 75 centimetres in length and weighs as much as 300 grams.

These remarkable creatures are distinguished by their bright emerald green skin, which appears after several hours of hatching from their eggs, and narrow white bands along their body. Their eyes are a striking reddish orange or pinkish gold in color.

The Fiji crested iguana's unique appearance is further enhanced by a taller spiny "crest" on its back, with spines as long as 1.5 centimetres running from the nape of the neck to the base of its tail.

The Fiji crested iguana can be found on several islands in Fiji, specifically in tropical dry forests on the rain shadow side of certain islands. These forests are one of the most threatened vegetation types in the Pacific.

The species is most commonly found on the island of Yadua Taba, where fewer than 4,000 individuals reside. This island is a National Trust of Fiji reserve, providing a safe habitat for the iguanas.

A small population of the Fiji crested iguana, fewer than 80 individuals, can be found on the small island of Macuata. This population is likely the most vulnerable due to its small size.

Other Fijian islands where evidence of the species has been recorded include Deviulau, Waya, Monuriki, Monu, Qalito (possibly extinct), Yaquaga, Yadua, Yaduataba, and Malolo Levu.

The Fiji crested iguana is a herbivore, feeding primarily on leaves, fruits, and flowers from trees and shrubs. Its diet varies with seasonal availability.

As a diurnal creature, the Fiji crested iguana spends its days under the shade of trees, seeking sunlight and heat on cooler days.

In times of threat, the Fiji crested iguana rapidly changes colour from green to black to intimidate its predator.

The Fiji crested iguana is a diurnal creature that tends to live under the shade of trees. It's not uncommon for them to seek sunlight/heat on days with cool temperature.

They have the ability to rapidly change colour from green to black when aroused. This colour change is a warning sign to potential predators.

The colours will vary depending on the severity of the situation, with bright green being standard, dark green being slightly more ominous, and black being an extreme warning. If the predator doesn't get the message from the colour change, the iguana will resort to an expansion of its neck and a bobbing of its head.

They will also pounce themselves towards the potential threat. This is a last resort, but it's a clear indication that the iguana is not to be trifled with.

Their long toes and tails help them keep balance while they move through the trees. It's impressive to watch them navigate their surroundings with such ease.

Fijian Crested Iguanas are entirely herbivorous, which means they only eat plants. Their diet consists mainly of leaves, fruits, and flowers from trees and shrubs.

These lizards don't get to choose their meals, as their diets vary with seasonal availability.

The Fiji crested iguana is a remarkable species that has been the focus of conservation efforts for many years. Its habitat on Yadua Taba Island was severely depleted by feral goats, but thanks to the removal of these invasive animals, the dry forest has recovered significantly.

Feral goats were introduced to Yadua Taba in 1972 and numbered over 200 by the late 1970s, causing extensive damage to the vegetation. The removal of these goats has allowed the forest to recover and has provided a safe habitat for the Fiji crested iguana.

Physical measures should be taken to protect the iguanas from introduced predators such as feral cats, rats, and mongooses. This includes removing them from the area, similar to the removal of the goats.

The government of Fiji has taken steps to eradicate Leucaena trees, which threaten the regeneration of native food trees for the iguanas. This is a crucial step in ensuring the long-term survival of the species.

Fiji's First Sanctuary is a remarkable achievement in conservation efforts. Located on Yadua Taba Island, it was established by the National Trust in 1980 to protect the Crested Iguanas' habitat.

Over 90% of the world's approximately 10,000 Crested Iguanas live on this island. The remaining less than 1,000 individuals are scattered among 10 other islands off the western coast of Viti Levu and Vanua Levu.

The sanctuary focuses on eradicating invasive plants and goats, conducting scientific research, and iguana population surveys. Community outreach and awareness programs are also an essential part of their conservation actions.

The National Trust has been working with partners since 2009 on captive breeding and reintroduction of Crested Iguanas to Monuriki island. They also conduct surveys of iguanas on other islands in the Fiji group.

The Fiji crested iguana is a species of lizard that's native to the island of Fiji.

They are relatively small, typically growing to about 20-25 inches in length.

These iguanas have a distinctive crest on their back that runs from the base of the neck to the tip of the tail.

They are herbivores, feeding on a diet of leaves, flowers, and fruits.

In captivity, they require a large enclosure with plenty of space to move around and climb.

A temperature range of 75-85°F (24-29°C) and high humidity levels are essential for their well-being.
