    Zoological Studies 56: 38 (2017) doi:10.6620/ZS.2017.56-38 Open Access Species Identification of Shed Snake Skins in Taiwan and Adjacent Islands Tein-Shun Tsai1,* and Jean-Jay Mao2 1Department of Biological Science and Technology, National Pingtung University of Science and Technology 1 Shuefu Road, Neipu, Pingtung 912, Taiwan 2Department of Forestry and Natural Resources, National Ilan University No.1, Sec. 1, Shennong Rd., Yilan City, Yilan County 260, Taiwan. E-mail: [email protected] (Received 28 August 2017; Accepted 25 November 2017; Published 19 December 2017; Communicated by Jian-Nan Liu) Tein-Shun Tsai and Jean-Jay Mao (2017) Shed snake skins have many applications for humans and other animals, and can provide much useful information to a field survey. When properly prepared and identified, a shed snake skin can be used as an important voucher; the morphological descriptions of the shed skins may be critical for taxonomic research, as well as studies of snake ecology and conservation. However, few convenient/ expeditious methods or techniques to identify shed snake skins in specific areas have been developed. In this study, we collected and examined a total of 1,260 shed skin samples - including 322 samples from neonates/ juveniles and 938 from subadults/adults - from 53 snake species in Taiwan and adjacent islands, and developed the first guide to identify them. To the naked eye or from scanned images, the sheds of almost all species could be identified if most of the shed was collected. The key features that aided in identification included the patterns on the sheds and scale morphology.

  • Identifying Intraspecific Variation in Venom Yield of Chinese Cobra (Naja Atra) from Ten Populations in Mainland China
    Asian Herpetological Research 2019, 10(1): 32–40 ORIGINAL ARTICLE DOI: 10.16373/j.cnki.ahr.180041 Identifying Intraspecific Variation in Venom Yield of Chinese Cobra (Naja atra) from Ten Populations in Mainland China Jianfang GAO1*, Yin YIN1, Yanfu QU2, Jin WANG2, Longhui LIN1, Hongliang LU1 and Xiang JI2 1 Hangzhou Key Laboratory for Animal Adaptation and Evolution, College of Life and Environmental Sciences, Hangzhou Normal University, Hangzhou 310036, Zhejiang, China 2 Jiangsu Key Laboratory for Biodiversity and Biotechnology, College of Life Sciences, Nanjing Normal University, Nanjing 210046, Jiangsu, China Abstract Detailed information on venom yield is helpful in preparing antivenoms and treating snakebites, but such information is lacking for many species of venomous snakes. The Chinese cobra (Naja atra) is a large sized, venomous snake commonly found in southeastern China, where it causes a heavy burden of snakebites. To examine the effects of various factors (morphology, sex, age, season, and geographical origin) on the venom yield in this snake, we collected venom samples of 446 individuals (426 adults and 20 neonates) from 10 populations of N. atra over an eight- year period. We used two variables, lyophilized venom mass (venom yield) and solid content of venom (% solids), to quantify the venom yield. We used linear regression analysis to check if venom yield was related to morphological factors, one-way ANOVA and one-way ANCOVA to detect the sexual, ontogenetic, and geographic variation in venom yield, and repeated-measures ANOVA to examine seasonal shifts in venom yield. Our results indicate that venom yield of N. atra is positively related to the morphological traits examined, with male snakes expelling more venom than females.

Tis study was designed to investigate the cytotoxicity and haemotoxicity of the Western barred (zebra) spitting cobra (Naja nigricincta nigricincta) venom to help explain atypical and inconsistent reports on syndromes by Namibian physicians treating victims of human ophidian accidents. Freeze-dried venom milked from adult zebra snakes was dissolved in phosphate bufered saline (PBS) for use in this study. Haemorrhagic and necrotic activity of venom were studied in New Zealand albino rabbits. Oedema-forming activity was investigated in 10-day-old Cobb500 broiler chicks. Procoagulant and thrombolytic activity was investigated in adult Kalahari red goat blood in vitro.
