Cordylus
Generally listed under CITES Appendix II for controlled trade; some species may be threatened by habitat destruction or over-collecting.·Ovoviviparous (live-bearing)
Cordylus, commonly known as girdled lizards, are a diverse genus of small to medium-sized spiny lizards native to Africa. These diurnal reptiles are characterized by their bony armor (osteoderms) and their ability to defend themselves by retreating into crevices. Most species are rock-dwellers, though some are arboreal or burrowing, and many exhibit social behaviors with males defending territories.
Key Facts
- ›All Cordylus species are diurnal and ovoviviparous (live-bearing).
- ›They possess osteoderms, which are bony plates in their skin, providing defense.
- ›Most species are rupicolous, meaning they live among rocks.
- ›Males of many species defend territories, and some species live in groups.
- ›Cordylus species are generally listed under CITES Appendix II, controlling their international trade.
- ›Their diversity is greatest in South Africa, with some species found in Angola and eastern Africa.

About Cordylus
The Genus Cordylus: African Girdled Lizards
The genus Cordylus encompasses a variety of small to medium-sized spiny lizards native to the African continent, collectively known as girdle-tailed or girdled lizards. These reptiles are characterized by their diurnal activity patterns and ovoviviparous reproduction, meaning they give birth to live young rather than laying shelled eggs. A defining feature of Cordylus species is the presence of osteoderms, which are flat bony plates embedded within their skin, providing a form of natural armor.
Habitat and Defense
Most species within the genus are rupicolous, preferring rocky environments where they can utilize crevices for shelter and defense. Some species have adapted to arboreal lifestyles or inhabit burrows. Their primary defense mechanism involves quickly retreating into these safe havens when threatened. Many Cordylus species also exhibit social behaviors, with males often defending territories, and some populations living in communal groups.
Distribution and Classification
The greatest diversity of cordylids is found in South Africa, with a presence extending into Angola and eastern Africa as far north as Ethiopia. The classification of the genus has seen revisions, with molecular phylogenetic studies leading to the reclassification of several species into new genera such as Hemicordylus, Karusaurus, Namazonurus, Ninurta, Ouroborus, and Smaug. Despite these taxonomic shifts, the genus Cordylus (in its restricted sense) continues to include a significant number of distinct species.
Conservation and Trade
Species within the Cordylus genus are generally listed under CITES Appendix II, which regulates their international trade to prevent overexploitation. While not all species are immediately threatened with extinction, those with limited geographic ranges can be vulnerable to habitat destruction and excessive collection for the pet trade. This controlled trade aims to ensure the long-term survival of these unique African lizards.

Frequently Asked Questions
What are girdled lizards?
Girdled lizards, belonging to the genus Cordylus, are a group of small to medium-sized spiny lizards found in Africa. They are known for their bony armor and their live-bearing reproductive method.
Where do girdled lizards live?
The greatest diversity of girdled lizards is found in South Africa. Some species extend into Angola and eastern Africa, as far north as Ethiopia.
How do girdled lizards defend themselves?
Girdled lizards defend themselves using their osteoderms, which are flat bony plates embedded in their skin, acting as armor. They also quickly retreat into rock crevices or burrows to escape predators.
Are girdled lizards endangered?
Girdled lizards are not necessarily threatened with extinction, but their international trade is controlled under CITES Appendix II to prevent overexploitation. Some species with limited ranges may be threatened by habitat destruction or over-collection for the pet trade.
What is the reproductive method of Cordylus species?
All species within the genus Cordylus are ovoviviparous, meaning they give birth to live young rather than laying shelled eggs.
Are there different types of girdled lizards?
Yes, there are numerous species within the Cordylus genus, with studies recognizing many distinct species. Some species previously placed in Cordylus have been reclassified into new genera like Hemicordylus, Karusasaurus, Namazonurus, Ninurta, Ouroborus, and Smaug.
