LUJA, Víctor H.; RODRIGUEZ-ESTRELLA, Ricardo  and  SINERVO, Barry. Observations on the diet of the two-stripped garter snake Thamnophis hammondii in an oasis of Baja California Sur, Mexico. Rev. Mex. Biodiv. [online]. 2013, vol.84, n.2, pp.697-700. ISSN 2007-8706.  https://doi.org/10.7550/rmb.32185.

Information is presented about the prey consumed by the two-stripped garter snake Thamnophis hammondii in a mountain oasis in Baja California Sur, Mexico. The diet of this threatened snake includes the Baja California treefrog Pseudacris hypochondriaca curta (native species), as well as an exotic fish: the red bellied tilapia Tilapia sp. cf. zilli. This exotic species has become invasive in Baja California Sur oases, displacing native fishes and becoming an important dietary resource to T. hammondii.
