The Opluridae, or Madagascan iguanas, are a family of moderately sized lizards native to Madagascar and Grande Comore. There are eight species in two genera, with most of the species being in Oplurus. The family includes species that live amongst rocks, some that live in trees, and two that prefer sandy habitats. All of the species lay eggs, and have teeth that resemble those of the true iguanas.[1][2] A study was done to identify the foraging mode of the oplurus species. The species was highly favored to be ambush foragers due to their low movement per min (MPM) and percent time spent moving (PTM) During rainy and dry seasons of the jardin botanique A of Ampijoroa forest. the two genera are easily distinguished. The smaller two Chalarodon species have a dorsal crest, particularly distinct in males, and has a smoother tail covered in similarly sized scales. Genus Oplurus has large segmented spiny scales, and no dorsal crest along the spine.[3][2]
A study of mitochondrial DNA sequences has dated the split between Opluridae and Iguanidae (within which Opluridae are sometimes classified as the subfamily Oplurinae) at about 165 million years ago, during the Middle Jurassic.[4] The study supported the monophyly of the expanded Iguanidae, and put Oplurinae in the basal position. This dating is consistent with a vicariant origin of the Madagascan iguanians, since Madagascar is believed to have separated from Africa (during the breakup of Gondwana) around 140 million years ago.[4]
