Assessment of visual acuity in Python regius using optokinetic response. (Veterinary ophthalmology (2025), PMID:39013796)
> Snakes are known for their unique abilities including infrared reception and their heavy reliance on heat sensors and vibrations. Infrared reception of snakes has gone under immense investigation; however, there have been very few studies that elaborate on their capacity to see. The goal of this study is to determine visual acuity of ball pythons (Python regius) by observing their optokinetic response (OKR). The OKR is a series of rapid saccadic and smooth pursuit movements of the eyes. It has been used for decades to determine visual acuity in multiple species such as humans, rats, and other nonmammalian species such as zebrafish and box turtles. Past studies have discovered that birds, reptiles, and amphibians achieve gaze stabilization by head and body movements, whereas in mammals and fish, gaze stabilization is conducted by eye movements. In this study, ball pythons were placed in a clear tube in a dark room, and a spinning black and white grating was projected in front of them. The size, direction, and velocity of the grating was manipulated which allowed their visual acuity to be determined. Our hypothesis is that P. regius would have a poor OKR response with low visual acuity due to their heavy reliance on other senses. Results show that P. regius does respond to visual stimuli, shows ocular saccadic movement in the direction of their stimuli, and has a relatively poor visual acuity when compared to other previously studied reptiles.

Species-specific variations in corticosterone concentrations in captive snake shed skins: implications for housing systems and welfare. (BMC veterinary research (2026), PMID:42032687)
> <h4>Background</h4>Captive reptiles may experience stress related to environmental conditions, and housing design is considered a key factor influencing their welfare. This study assessed corticosterone concentrations in shed skins as a non-invasive biomarker of chronic stress in three commonly kept snake species-Boa imperator, Python regius, and Pantherophis guttatus-maintained either in low-stimulus rack systems or enriched terraria. Shed skins were collected from privately owned snakes and from a breeders, prepared following standardized protocols, and analyzed using ELISA assays. Non-parametric statistical methods (Mann-Whitney U tests) were applied due to non-normal data distribution.<h4>Results</h4>Variation in corticosterone concentrations was observed among the studied species, with higher values recorded in P. guttatus compared to B. imperator and P. regius. The effects of housing conditions differed between species. In P. regius, individuals kept in enriched terraria exhibited higher corticosterone concentrations than those housed in rack systems, whereas the opposite pattern was observed in P. guttatus, where snakes maintained in rack systems showed elevated corticosterone levels. No clear housing-related differences were observed in B. imperator. Species-specific relationships between enclosure volume and corticosterone concentration were identified, with positive associations in P. regius, negative associations in P. guttatus, and no apparent relationship in B. imperator.<h4>Conclusions</h4>The study indicates interspecific variation in corticosterone deposition in snake shed skin and demonstrates that the relationship between housing conditions and corticosterone levels is species-specific. More active species, such as P. guttatus, may be more sensitive to spatial restriction and limited environmental complexity, whereas less active species, such as P. regius and B. imperator, may respond differently to housing conditions. These findings underscore the importance of species-tailored welfare guidelines, suggesting that enclosure design and enrichment strategies should be adapted to the behavioural ecology and physiological characteristics of individual snake species rather than applied uniformly across taxa.

Uric Acid Monohydrate Nanocrystals: An Adaptable Platform for Nitrogen and Salt Management in Reptiles. (Journal of the American Chemical Society (2025), PMID:41123193)
> Both avian and nonavian reptiles excrete excess nitrogen in solid form─colloquially termed "urates"─as an evolutionary adaptation that aids in water conservation. Yet, there are many open questions regarding the composition, structure, and assembly of these biogenic materials. Here, analyses of urate excretions from ball python (<i>Python regius</i>) and 20 other reptile species reveal a clever and highly adaptable system employed to handle both nitrogenous waste and salts. Primitive species excrete urates consisting of 1-10 μm microspheres of turbostratic uric acid monohydrate (UAM) nanocrystals. The nanocrystals' high surface area and ionizable nature provides a platform to coeliminate substoichiometric concentrations of various salts through surface-ion pairing. In contrast, the granular urates produced by species from more advanced snake lineages are phase mixtures consisting of predominantly ammonium urate hydrate (AUH) and smaller amounts of other crystalline forms. Identification of microspheres as a minor but highly soluble component of these excretions suggests their likely role as reactive precursors to AUH, a hypothesis supported by in vitro experiments. Importantly, this points to a previously unrecognized physiologic function of uric acid, namely the ability to sequester ammonia by transforming it into a solid. The potential implications of this function in other species are discussed.
