A spider's fangs are natural injection needles, making them perfectly suited for piercing the skeletons of prey and delivering a kiss of venom, a new

study finds.
The toothy barbs of a large wandering spider are curved in order to hold the spider's prey in place, and their conical shape helps them resist deformation. Understanding the biomechanics of spider fangs could inspire new medical injection devices, researchers say.
"For biomedical applications, for example, the spider fang may lead to the design of new infusion techniques, new blood-bypassing instruments and many other life-saving technologies," said Benny Bar-On, a biomaterials scientist at the Max Planck Institute of Colloids and Interfaces in Germany and co-author of the study published today (May 27) in the journal Nature Communications.
