Armadillo girdled lizard
|Armadillo Jalen lizard|
(F. Boie, 1828)
It is also commonly known as typical girdled lizard, armadillo lizard, golden armadillo lizard, and armadillo spiny-tailed lizard.
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 usual size ranges from 7.5 to 9 cm (3 to 3.5 in) in snout-vent length (SVL). It may grow to a maximum size of 10.5 cm (4.1 in) SVL. As adults, they have such a strong bite force, that they can break their jaws.
This lizard is relatively common in the pet trade. It can be found in pet stores and it is quite easy to breed in captivity. Wild populations are threatened by collecting for sale in the pet trade. It can live up to 10 years in captivity, or slightly longer in rarer cases.
It is diurnal. It hides in rock cracks and crevices. It lives in social groups of up to 30 to 60, but usually fewer. Males are territorial, protecting a territory and mating with the females living there.
The armadillo girdled lizard feeds mainly on small invertebrates, such as insects and spiders. In the wild, its most common prey items are the termites Microhodotermes viator and Hodotermes mossambicus.
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 name.
