Two related species of species of frugivorous skinks, the night phantom skink("Tristiidon lunata") and the day phantom skink("Tristiidon sol") are the only lizards on the island. Both are flat-tailed and are surprisingly large for arboreal lizards. Although they are commonly related with Tristan da Chuna(hence the name),They are also native to St Helena and Accencion and released in 11 tropical nations, including the states of Florida and Hawaii. The main distinction between the two species is their time of activity, being nocturnal and diurnal respectively. The day phantom skink is also a common pet in Brazil.
