Creature Feature XIII: Two Types of Vipers

My new piece for Creature Feature is about two snakes that are a looming presence in my life in the field: the saw-scaled viper and the cottonmouth. The piece talks about research by Harvey Lillywhite and his lab on the unusual feeding biology of island cottonmouths, and also a paper, Barlow et al. 2009, on the coevolution of diet and venom composition in saw-scaled vipers.
