Reptiles may bask for reasons other than thermoregulation. One alternative is to regulate homeostasis of vitamin D3, a hormone essential to the health of many reptiles. Maintenance of vitamin D3 homeostasis requires either regulation of exposure to ultraviolet radiation (UV) or ingested vitamin D3. However, the prey items of most vertebrates tend to be low in vitamin D3. Thus, basking may be the primary opportunity for vitamin D3 regulation. We tested the hypothesis that panther chameleons… 
Natural exposure to ultraviolet-B radiation in two species of chameleons from Madagascar.
TLDR
The results suggest that both C. brevicorne and C. nasutum can be classified as Ferguson Zone 1 species, and should be provided with aUV-B gradient in captivity that offers access to UV-B radiation as well as adequate shaded refuge.
Ultraviolet Light Exposure and Response to Dietary Vitamin D3 in Two Jamaican Anoles
TLDR
An initial UV photo-regulatory adjustment to high dietary vitamin-D3 but a slow return to greater reliance on UVB-induced endogenous vitamin D3 production is suggested.
Summer and Winter Seasonal Changes in Vitamin D Status of Captive Rhinoceros Iguanas (Cyclura cornuta)
TLDR
Although the iguanas seemed robust physically, had acceptable calcium and phosphorus blood concentrations, and successfully reproduced throughout the 2 yr monitoring period, it is not recommend extended periods of deprivation of UVB and vitamin D supplementation in winter for rock iguana until minimally sufficient vitamin D status is more rigorously established.
Evaluating the Physiologic Effects of Short Duration Ultraviolet B Radiation Exposure in Leopard Geckos (Eublepharis macularius)
TLDR
It is demonstrated that short duration exposure to UVB light can lead to increased circulating 25-hydroxyvitamin D3 concentrations in leopard geckos.
Cutaneous Vitamin D Synthesis in Carnivorous Species
The aim of this study was to investigate the differences of the ability to synthesize sufficient amounts of vitamin D in the skin of different carnivorous species. To this endskin tissue of 22
EFFECTS OF A LIGHT-EMITTING DIODE ON THE PRODUCTION OF CHOLECALCIFEROL AND ASSOCIATED BLOOD PARAMETERS IN THE BEARDED DRAGON (POGONA VITTICEPS)
TLDR
The effect of different bulbs to promote synthesis of cholecalciferol (vitamin D3) in the bearded dragon was evaluated and overall plasma concentration for 25OHD3 in the LED group was greater than for the UVB and the UVBN groups.
Research Article Basking Behaviour and Ultraviolet B Radiation Exposure in a Wild Population of Pelophylax lessonae in Northern Italy
TLDR
It is shown that wild frogs inhabit a UV-B microclimate defined by physical features of their habitat and by the basking behaviour of the animals themselves, which may encourage the future gathering of such wild environmental data, which could be fed directly into ex-situ programs.
Influence of Sunlight on Vitamin D and Health Status in Green (Chelonia mydas) Sea Turtles with Fibropapillomatosis
TLDR
It is determined that exposure to more sunlight influences plasma vitamin D levels in sea turtles brought into a rehabilitation facility and increasing sun exposure in rehabilitation facilities may enhance health and recovery in green turtles with FP.
Ultraviolet radiation on innate immunity and growth of broad-snouted caiman (Caiman latirostris): implications for facilities design.
TLDR
The data demonstrate that artificial UV should be considered as a potential hazard for captive crocodilians if it is not properly managed, and this should be taken into account in the general design of facilities for reptilian husbandry.
How much UVB does my reptile need? The UV-Tool, a guide to the selection of UV lighting for reptiles and amphibians in captivity.
TLDR
The UV-Tool contains an editable and expanding database of the microhabitat requirements and basking behaviour of reptile and amphibian species, as derived from field studies, or inferred from observed behaviour in captivity.

Do Panther Chameleons Bask to Regulate Endogenous Vitamin D3 Production?
TLDR
Depending on dietary intake of vitamin D3, chameleons adjusted their exposure time to UV‐B irradiation as if regulating their endogenous production of this vital hormone, and Vitamin D3 photoregulation seems to be an important additional component of the function of basking.
Indoor husbandry of the panther chameleon Chamaeleo [Furcifer] pardalis: Effects of dietary vitamins A and D and ultraviolet irradiation on pathology and life‐history traits
TLDR
To assess the importance of diet and light for indoor maintenance, hatchling panther chameleons were reared for 1 year on crickets fed diets that differed in vitamin concentrations and in different light environments, and low vitamin A drastically reduced reproduction in both sexes.
Effects of Artificial Ultraviolet Light Exposure on Reproductive Success of the Female Panther Chameleon (Furcifer pardalis) in Captivity
TLDR
The results and techniques for light quality assessment are interpreted, with recommendations for practical application by the herpetoculturist desiring to successfully breed panther chameleons in captivity.
Vitamin D supplementation increases the attractiveness of males' scent for female Iberian rock lizards
TLDR
It is suggested that the allocation of vitamins and other essential nutrients to either visual (e.g. carotenoids) or chemical ornaments might be the common basis of honest sexual displays in many animals.
Vitamin D and Skin Physiology: A D‐Lightful Story
TLDR
The associations regarding increased risk of common deadly cancers, autoimmune diseases, infectious diseases, and cardiovascular disease with living at higher latitudes and being prone to vitamin D deficiency should alert all health care professionals about the importance of vitamin D for overall health and well being.
Ultraviolet Exposure and Vitamin D Synthesis in a Sun‐Dwelling and a Shade‐Dwelling Species of Anolis: Are There Adaptations for Lower Ultraviolet B and Dietary Vitamin D3 Availability in the Shade?
TLDR
The ability to behaviorally regulate UV‐B exposure, as shown for the panther chameleon, would benefit both species of Anolis and should be investigated, and the possibility that adaptations for photobiosynthesis of vitamin D and for protection from skin damage could involve independent mechanisms needs investigation.

TLDR
It is likely that the membrane entrapment of previtamin D3 in its s-cis,s-Cis conformation is responsible for the markedly enhanced conversion of prev Vitamin D3 to vitamin D3, which ensures the critical supply of vitamin D2 to poikilothermic animals such as iguanas.
Photobiosynthetic Opportunity and Ability for UV-B Generated Vitamin D Synthesis in Free-Living House Geckos (Hemidactylus turcicus) and Texas Spiny Lizards (Sceloporus olivaceous)
TLDR
This is the first documentation that mostly nocturnal geckos may rely on photobiosynthesis of vitamin D3 and that they might have a more sensitive mechanism than diurnal lizards to compensate for their limited exposure to natural UVB radiation.
Sunlight regulates the cutaneous production of vitamin D3 by causing its photodegradation.
TLDR
Vitamin D3 proved to be exquisitely sensitive to sunlight, and once formed in the skin, exposure to sunlight resulted in its rapid photodegradation to a variety of photoproducts, including 5,6-transv vitamin D3, suPRasterol I, and suprasterol II.
