The orange-bellied swamp snake (Tretanorhinus nigroluteus) is considered a rare species in Mexico; there are few specific records of its presence in the country. They are known to feed on amphibians (anurans) and fish of different species (Families Gobidae and Poecilidae). We report the first record of freshwater snails (Pachychilus largillierti) as prey of T. nigroluteus.

Keywords : Dipsadidae; predation; freshwater snail; mangrove snake.
