摘要

Predation events known as saurophagy occurs when lizards are involved as prey. Whether by cannibalism or saurophagy such events has been well documented in the last years. This paper report a predation event on Iguana iguana by B. constrictor recorded in a fluvial island in the Amazonas River, Brazil. Also, provides a list of saurophagy events involving Boa constrictor as predator. During a field trip we found an individual of B. constrictor in the process of ingesting a common green iguana ( I. iguana ), swallowing the headfirst on an upland forest. We found a total of eight lizards as prey of B. constrictor , belonging to three families: Iguanidae, Teiidae e Tropiduridae.
