Abstract
The benefit of UV light for reptiles is a long, much debated area and results and opinions are often mixed. To investigate the growth and behaviour effects of UVB exposure on Pantherophis guttatus, twelve snakes were used. These were split into three groups of four snakes, and exposed to different levels of UVB; 2% UVB (1), 6% UVB (2) and a control group (3). Due to health reasons, two snakes had to be removed from group 2, therefore number of participants was: group 1 – four snakes, group 2 – two snakes, group 3 – four snakes. Results showed no significant difference in growth for snake length. However, a significant difference was noted in snake weight between groups 1 and 3, the potential reasons for which are discussed. No significant difference was found in basking high, however a significant difference was observed in basking medium (the best position for UVB exposure) between groups 1 and 2. The control group was observed more times than group 1 in this behaviour, perhaps in attempts to access UVB, although this was not statistically significant. Again, the potential reasons for this behaviour are discussed. Group 1 were observed significantly more actively moving than group 2, and also group 3, but this was not statistically significant. Group 1 were observed in the UVB basking area on level 3 considerably more times than group 2, but only slightly more than group 3; 39%, 8% and 35% respectively. P. guttatus are known to be able to synthesis vitamin D3 through exposure to UVB and this may also influence other metabolic processes in this species. This study shows that P. guttatus will voluntarily expose themselves to UVB, the effects of which can increase activity levels. This increase in activity levels may be due to the possible influence of UVB on metabolic processes. Therefore, a low level of UVB, such as a 2% bulb, can be provided to P. guttatus without detriment.
