The Jamaican Anolis opalinus has different perch height characteristics depending on locality. Toward the center of the island, around Mandeville, A. opalinus characteristically perches low, being classified as a trunk—ground species. In Kingston, however, A. opalinus perches high, classified as a trunk—crown species, Evidence indicates the Kingston A. opalinus would also perch low except that interaction with Anolis I. Lineatophus forces A. opalinus into perch sites higher than appear to be the species' preference.
