The genus Spondylurus – vernacularly known as the Antillean four-lined skinks – is a Neotropical skink taxon including many species that are classified by four (occasionally three to six) dark dorsolateral stripes. This characteristic is known to fade in older individuals and colors when preserved shift from tans and browns to greens and blues, often causing confusion as to the true color. Many of these species are extinct or endangered resulting from invasive predators such as the mongoose.
