*[Paraphrased derived summary — non-Open-Access source.]* African spurred (sulcata) tortoises are common pets but need calcium-fortified, fibrous, plant-based diets and broad-spectrum lighting; they grow from 5-cm (2-inch) hatchlings to over 100 kg adults, so need large (preferably outdoor) enclosures, which is hard in cooler northern areas. *[Paraphrased derived summary — non-Open-Access source.]* UVB light (290–300 nm) is especially important for most day-active lizards and chelonians for vitamin D3 synthesis and calcium regulation. *[Paraphrased derived summary — non-Open-Access source.]* Humid microclimates are often critical for arid species (e.g. tortoises, leopard geckos) to reduce shell pyramiding and abnormal sheds.
