Dragonskins are striking monitor lizards that recently colonized the island but have evolved into a new species. Having likely arrived on rafts of vegetation or driftwood from somewhere in Southeast Asia, they developed brilliant red scales that are even more vivid in the breeding season. The precise function of the markings is not clear, though it may be to startle larger predators. Both sexes are brightly colored.
Dragonskins feed on eggs and smaller creatures, like certain seabirds, they find along the rocky shore and on the cliffs they nimbly climb.
