Armadillo girdled lizard


The armadillo girdled lizard, also commonly known as the armadillo lizard, the Golden-armadillo lizard, or the armadillo spiny-tailed lizard, is a species of lizard in the family Cordylidae. The species is endemic to desert areas along the western coast of South Africa. In 2011, it was moved to its own genus based on molecular phylogeny, but formerly it was included in the genus Cordylus.

Description

The armadillo girdled lizard can be a light brown to dark brown in coloration. The underbelly is yellow with a blackish pattern, especially under the chin. Its size can range from in snout-vent length. It may grow to a maximum size of SVL.

Distribution and habitat

O. cataphractus is endemic to the Succulent Karoo biome in the Northern and the Western Cape provinces of South Africa, where it occurs from the southern Richtersveld to the Piketberg Mountains and the southern Tankwa Karoo. It inhabits rock outcrops and mountain slopes, preferably on sandstone substrate.

Ecology

Diet

The armadillo girdled lizard feeds mainly on small invertebrates, such as insects and spiders, but sometimes also may take plant material. In captivity, it is commonly fed crickets. In the wild, its most common prey items are termites, especially Microhodotermes viator and Hodotermes mossambicus.

Behavior

The armadillo girdled lizard is diurnal. It hides in rock cracks and crevices. It lives in social groups of up to 30 to 60 individuals of all ages, but usually fewer. Males are territorial, protecting a territory and mating with the females living there.
The armadillo girdled lizard possesses an uncommon antipredator adaptation, in which it takes its tail in its mouth and rolls into a ball when frightened. In this shape, it is protected from predators by the thick, squarish scales along its back and the spines on its tail. This behavior, which resembles that of the mammalian armadillo, gives it its English common names.

Reproduction

The female armadillo girdled lizard gives birth to one or two live young; the species is one of the few lizards that does not lay eggs. The female may even feed her young, which is also unusual for a lizard. Females give birth once a year at most; some take a year off between births.

Conservation

The species Ouroborus cataphractus was classified by the IUCN as Vulnerable until 1996, but has since been downgraded to Least Concern. This is mostly due to a general cessation of collection for the pet trade, which was a significant drain on populations but is now illegal. The armadillo girdled lizard is thought to be somewhat susceptible to fluctuations in its primary foodsource, which in turn can be impacted by climatic events such as changes in rainfall patterns, as well as to habitat changes through invasive alien plant species and poor fire management.
