The armadillo girdled lizard (Ouroborus cataphractus),

phylogeny, but formerly it was included in the genus Cordylus.[2][4]

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 7.5 to 9 cm (3.0 to 3.5 in) in snout-vent length (SVL). It may grow to a maximum size of 8 in (20 cm) SVL.[3]

Distribution and habitat

O. cataphractus is endemic to the

Tankwa Karoo. It inhabits rock outcrops mountain slops, preferably on sandstone substrate.[1]

Ecology

Diet

The armadillo girdled lizard feeds mainly on small invertebrates, such as insects and spiders, but sometimes also may take plant material.[3][5] In captivity, it is commonly fed crickets. In the wild, its most common prey items are termites, especially Microhodotermes viator[3] and Hodotermes mossambicus.[5] Individuals in larger social groups tend to eat more termites than those in smaller groups[6]

Behavior

The armadillo girdled lizard is

territorial, protecting a territory and mating with the females living there.[5]

Ourobouros

The armadillo girdled lizard possesses an uncommon

its tail in its mouth when frightened. In this shape, it is protected from predators by the thick, squarish scales along its back and the spines on its tail.[3] This behavior, which resembles that of the mythical ouroboros and of the mammalian armadillo, gives it its taxonomic and English common names.[3]

Reproduction

The female armadillo girdled lizard gives birth to one[3] or two[5] 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.

One hundred and six individuals from 27 groups were marked and recaptured regularly from May until September 2002. The group that was greater in fidelity had a greater neighboring distance. While the group that was less in fidelity had a less neighboring distance. The neighboring distance correlates to the fidelity of the armadillo girdled lizard species.[7]

Males follow either a prenuptial or postnuptial reproductive cycle. The more common cycle is prenuptial with high sperm count being in the fall and winter seasons. In the postnuptial cycle, males produce the most sperm in the late summer season.[8]

Conservation

The species Ouroborus cataphractus is classified by the

IUCN as near threatened. 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.[1][3][5] The armadillo girdled lizard is thought to be somewhat susceptible to fluctuations in its primary foodsource (termites), 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.[1]
