Objective: To make a description of a predatory event by the Micrurus hemprichii ortonii coral snake on the Ninia hudsoni snake. Scope: Contribution to the knowledge of the natural history of Neotropical snakes, particularly in relation to trophic interactions. Methodology: Dissection in the laboratory. Main result: This is the first record of the trophic interaction between M. h. ortonii and N. hudsoni. Conclusions: The relation between the total length of the prey and the snout-vent length of the predator was very high (>90%), indicating that this species of coral snake can ingest preys of great volume and size in relation to its own body.
