Predation on a tropical house gecko, Hemidactylus mabouia by a juvenile colubrid snake, Chironius bicarinatus, in a Brazilian Atlantic Rainforest area.

Davor Vrcibradic, Alexia Eisfeld

Resumen


Snakes in the Neotropical genus Chironius are mainly batrachophagous, and tend to consume relatively small prey. We present a report of a juvenile Chironius bicarinatus that had ingested a house gecko (Hemidactylus mabouia) corresponding to ca. 62% of its preserved body mass. The ingestion of such a large prey item is unusual for a snake of the genus Chironius, as is the consumption of lizards. Consumption of unusually large prey items may be more common in young snakes than in adults, possibly due to a lower availability of prey of appropriate size and/or to a lower capacity to evaluate the size of potential prey.
