legless gecko? wow never heard of that. honestly i have only seen legless skinks. being a legless gecko, to opposite end of the gecko evolution spectrum, is really kind of odd. geckos are known for their specialized feet and in this case the complete lack of!
wonder who they are related to? anyone have this info?
Leglessness and limb reduction is a recurring theme in squamate evolution. Dibamids, geckos, amphisbaenians, anguids, scinids, cordylids, lacertids, gymnophthalmids, and snakes (of course) have all lost limbs.
The family Pygopodidae is most closely related to Carphodactylidae, which includes Nephrurus, Phyllurus, Carphodactylus (and others). Diplodactylidae (Strophurus, Diplodactylus, Oedura, Rhacodactylus, etc) is the sister group to this nearly exclusively Australian lineage (according to recent papers). This is why if you consider knobtails to be geckos, and crested geckos to be geckos, and tokay geckos to be geckos, pygopods are also geckos.
