Brachylophus

Brachylophus is a genus of lizards in the family Iguanidae, commonly known as Fiji iguanas. Endemic to the islands of Fiji, these arboreal reptiles inhabit tropical forests, woodland edges, and occasionally gardens and plantations. The genus comprises several described species that occupy a range of elevations across multiple Fiji islands.

Adults are generally medium-sized and slender, with long tails. Coloration is highly variable and often sexually dimorphic. In many species, males assume bright greens, blues, or turquoise during the breeding season, while females are duller. Some species exhibit banding or mottled patterns that provide camouflage among leaves and branches.

Brachylophus lizards are primarily herbivorous, feeding on leaves, flowers, and fruit, with occasional consumption of insects. They are diurnal and spend much of their time in trees, basking on exposed perches and moving between foliage in search of food.

Reproduction is sexual and eggs are laid in clutches of a few to several eggs. Incubation periods are influenced by temperature and humidity, typically ranging from several weeks to a few months.

Conservation status varies by species. Habitat loss, introduced mammals, and predation have reduced population sizes in several locales. Some species are protected within Fiji's reserves, and captive breeding and habitat restoration efforts have been undertaken aimed at stabilization and recovery of extant populations.
