Thamnophis hammondii foraging behavior
Thamnophis hammondii is considered one of the most aquatic of the gartersnakes and is closely associated with creeks and impoundments (Fitch 1940. Univ. California Publ. Zool. 44:1–150) with a diet consisting largely of both the larvae and transformed stages of amphibians (Spea, Bufo, Rana, Pseudacris) and small fish (Oncorhynchus, Gasterosteus, Eucyclogobius, and Cottus) (Jennings and Hayes 1994. Amphibian and Reptile Species of Special Concern in California. Final report contract no. 8023, California Department of Fish Game. 255 pp.; Rossman et al. 1996. The Garter Snakes: Evolution and Ecology. Univ. of Oklahoma Press, Norman. 332 pp.). Little is known regarding the foraging behavior of T. hammondii (Rossman et al., op. cit.). Herein, we describe the details of a predation sequence (approach, strike, and capture) observed in a natural setting.
