This phenomenon is known in many different species and has been observed recently in some frogs and salamanders (Taboada et al., 2017; Lamb & Davis, 2020) and reptiles such as sea turtles (Gruber & Sparks, 2015), chameleons (Pr?tzel et al., 2018), sea snakes (Seiko & Terai, 2019) and to date in six gecko species; Chondrodactylus bibronii (Sloggett, 2018), Cyrtodactylus baluensis (Jeng, 2019), Cyrtodactylus quadrivirgatus (Top et al., 2020), Hemidactylus parvimaculatus (Mendyk, 2021), Kolekanus plumicaudus (Pinto et al., 2021) and Pachydactylus rangei (Pr?tzel et al., 2021). The latter is an interesting case as the flourescence arises from iridophores. Here we report a study of biofluorescence in two further gecko species Hemidactylus turcicus (L., 1758) and Tarentola mauritanica (L., 1758).
查看更多>>摘要：The agile frog, Rana dalmatina Fitzinger 1838, is widely distributed in western, central and south-eastern Europe (Speybroeck et al., 2016). It lives mainly in deciduous and mixed forests and adjacent meadows. The colouration of this slender and long-legged ranid is generally uniform brown, light brown or beige above, often reddish or yellowish, with a few darker markings.
查看更多>>摘要：The oriental vine snake, Ahaetulla prasina Boie, 1827, is a wide ranging Indo-Malayan species (Uetz et al., 2021) exhibiting polymorphic colouration, typically green but greyish, brownish or orange-yellowish (Amber et al., 2017; Das, 2018). It is an ovoviviparous species known to produce 4-10 neonates with total lengths of 240-490 mm (Das, 2018). In the past the colour of neonates has very rarely been commented upon although the only reference we are aware of states that they are light brown (Lim & Tat-Mong, 1989).

They are found primarily in the Gulf of Mexico, Caribbean, and in warmer Atlantic waters but have long been known to visit British and European waters as vagrants (Ernst & Barbour, 1989).
查看更多>>摘要：Pigmentary abnormalities occur when there is an absence or predominance of certain pigment cells (chromatophores) or variations in the production of pigments within them (Duellman & Trueb, 1994). In amphibians, the most frequent cases of abnormal pigmentation are albinism and leucism, which result from deficient production of melanin (Lunghi et al., 2017). Albinism is a genetic disorder characterised by partial or complete lack of skin and eye pigmentation (Bechtel, 1995) and xanthism, the subject of this report, is a type of albinism in which individuals produce predominantly yellow pigments (Stephenson & Drace, 2014).
查看更多>>摘要：The common house gecko Hemidactylus frenatus is a relatively small (SVL 51 mm) arboreal lizard. It is native to south-east Asia with a widespread distribution in the Pacific islands; it has also been introduced widely elsewhere by anthropogenic means (Rodda, 2020). There are numerous records of various species of spider predating lizards (Bauer, 1990; Koch & Arida, 2017; van Blerk et al., 2020; Tripathy & Priyadarshini, 2022), including Hemidactylus sp. (Purkayastha & Sourav, 2011; Lanschi & Ferreira, 2012; Turner, 2018). However, these have not included the Asian hermit spider Nephilengys malabarensis (Araneae: Nephilidae).
