This project aims to generate unprecedented insights into the fangs of venomous snakes, focusing on elapids (taipans, tiger snakes etc). We will examine fang shape diversity, correlation with behavior and ecology, evolutionary history, and biomechanical properties. Data will be collected using cutting-edge micro-CT technology and analysed using 3D geometric morphometrics, computer simulations, and advanced phylogenetic techniques. This should greatly improve understanding of the evolution of venom fangs in all snakes. Other benefits include a large 3D reference database allowing identification of fossil fangs, with applications for studies of past climates, and a characterisation of fang biomechanics, relevant to biodesign and biomimicry.

该项目旨在对有毒蛇的牙产生前所未有的见解，重点是弹性（taipans，tiger蛇等）。 我们将研究尖的形状多样性，与行为和生态学，进化史和生物力学特性的相关性。数据将使用尖端的微型CT技术收集，并使用3D几何形态计量学，计算机模拟和晚期系统发育技术进行分析。这应该大大提高人们对所有蛇中毒牙的演变的理解。 其他好处包括一个大的3D参考数据库，允许鉴定化石尖牙，并应用了过去气候的研究以及与生物设计和仿生型有关的牙型生物力学的表征。
