Peruvian Eyelash Iguana

Ctenoblepharys adspersa is a liolaemid lizard within the monotypic genus Ctenoblepharys. It is endemic to the arid western coast of Peru. It is locally known as cabezona.

The species is secretive and arenicolous, meaning that it inhabits sandy areas. It is primarily found along coastal sand dunes and beaches, but also hyper-arid habitats, ephemeral streambeds, and Tillandsia groves further inland, as far as the Andean foothills. Much of its biology and ecology is unknown, though it is known to be oviparous (egg-laying) and excavates burrows up to a meter in length. It feeds on a wide variety of insects, the most common being hymenopterans (wasps, ants, etc.), followed by coleopterans (beetles) and insect larvae. Activity levels are greatest in the morning (9–11 AM) and in the afternoon (3–4 PM).
