The species is closely related to the Fiji crested iguana and B. bulabula.

The Fiji crested iguana is oviparous and has one of the longest incubation periods of any reptile at 189 days.

After the discovery of the Fiji crested iguana, the island was declared a sanctuary and all but a few goats were removed and fires banned.

Fiji crested iguanas are herbivorous feeding on the leaves, fruit, and flowers of trees and shrubs, particularly hibiscus flowers of the Vau tree (Hibiscus tiliaceus).

When Fiji 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.

The Fiji crested iguana (Brachylophus vitiensis) is a critically endangered species of iguana native to some of the northwestern islands of the Fijiian archipelago, where it is found in dry forest.

The Fiji crested iguana (Brachylophus vitiensis) is a critically endangered species of iguana native to some of the northwestern islands of the Fijiian archipelago, where it is found in dry forest.

Yadua Tabu is a protected sanctuary for the Fiji Crested Iguana, Brachylophus vitiensis, and also contains a strand of dry littoral forestry, almost completely lost in the rest of Fiji.

As it turned out, the iguanas filmed on Fiji were a species hitherto unknown to science; this was noted by the herpetologist John Gibbons when he watched the film, and after traveling to the island where the iguanas were filmed, he described the Fiji Crested Iguana (Brachylophus vitiensis) in 1981.
