A Resistant Predator and Its Toxic Prey: Persistence of Newt Toxin Leads to Poisonous (Not Venomous) Snakes
@article{Williams2004ARP, title={A Resistant Predator and Its Toxic Prey: Persistence of Newt Toxin Leads to Poisonous (Not Venomous) Snakes}, author={B. L. Williams and E. D. Brodie and E. I. Brodie}, journal={Journal of Chemical Ecology}, year={2004}, volume={30}, pages={1901-1919} }
The Common Garter Snake (Thamnophis sirtalis) preys upon the Rough-skinned Newt (Taricha granulosa), which contains the neurotoxin tetrodotoxin (TTX) in the skin. TTX is toxic, large quantities are present in a newt, and highly resistant snakes have the ability to ingest multiple newts; subsequently snakes harbor significant amounts of active toxin in their own tissues after consuming a newt. Snakes harbor TTX in the liver for 1 mo or more after consuming just one newt, and at least 7 wk after… Expand
