When Fijian crested iguanas first hatch from their eggs they are dark green, but after several hours their skin becomes bright emerald green and narrow white bands can be seen along their body. Their distinctive crest is also present from birth and can grow up to 1.2cm long. Juvenile crested iguanas look just like miniature versions of their parents. Females are the same in appearance as the males. Adults grow to 70-80cm and weigh 300-350 gms.
Crested iguanas are a rare species restricted to the rain shadow forests of a few scattered islands in the Fiji Island group, including the tiny island of Yadua Taba. The Fijian crested iguana on Yadua Taba Island is the only protected population in the world. Due to the small size of each island population, the species as a whole is extremely vulnerable. Their life is spent mostly off the ground amongst the branches and leaves of their forest home.
A Fijian crested iguana's diet is mainly herbivorous, eating a wide variety of leaves, shoots and fruits from trees and shrubs. They will also eat small insects from time to time. Their favorite food is from the Vau tree which bears sweet hibiscus flowers and is also the species of tree they spend most of their time in.
Mating season for the Fijian crested iguana is from March through to April. They have the longest incubation period of any iguana in the world - up to nine months. The eggs are white and leathery, with the average number of eggs in a clutch being four. A couple of weeks before hatching, a brown oval mark appears on the surface of the egg. This marks the spot where the baby crested iguana's head will pop out of the shell. It can take up to a whole day for the baby iguana to completely hatch.
Fijian Crested Iguana Profiles
Kermit is one of our gorgeous Fijian crested iguanas. He was born in 2005 and you have to admit, he is an absolutely amazing looking animal.
We are very fortunate to have these iguanas here at Australia Zoo, especially given they are amongst the most critically endangered lizards on the planet. They are only found on three islands in the west of Fiji.
Kermit is great, he loves coming out for walks around the zoo and loves to have his photo taken. So much so, Kermit is often featured in our Australia Zoo calendars.
G'day, my name is Teddy. I'm a critically endangered Fijian crested iguana! I am a spectacular emerald green colour, so you might need a keen eye to spot me, as I am perfectly designed to camouflage amongst the trees. I have lots of character and can be very cheeky! I spend my days eating all of my favourite fruits, veggies, leaves and sometimes I even enjoy an insect or two. I am very important here at Australia Zoo because my species is in big trouble in the wild. Steve and Terri dedicated much of their time researching my wild counterparts and they even discovered previously unknown populations of Fijian crested iguanas. You- beauty!
