Bibron’s Thick-toed Gecko, also known as Bibron’s Giant Gecko, is a nocturnal reptile occurring in South Africa’s Western, Eastern and Northern Cape, Free State and North West Provinces, and marginally into adjacent parts of Botswana and Namibia. Here it inhabits rocky outcrops and human habitations in Karoo and semi-desert scrublands. It feeds on a wide variety of insects, other invertebrates, and even smaller lizards, often hunting around the lights of buildings at night. They are often found in colonies but are territorial and aggressive to each other, the males especially so, and they will also readily bite to defend themselves against predators and humans. Bibron’s Gecko is one of the largest geckos in South Africa, growing to between 15 and 20cm in length (including the tail, which makes up about half their total length). Adult females typically lay two clutches of two eggs each per year, hiding them in crevices or under bark.
