T2 - even small boids may be a potential threat to small-bodied platyrrhines T1 - Predation of a squirrel monkey (Saimiri sciureus) by an Amazon tree boa (Corallus hortulanus) hortulanus may be limited to capturing small platyrrhines such as callitrichines.", The evidence indicates that the predation event occurred at the end of the afternoon or early evening, and that, while capable of capturing an agile monkey like Saimiri, C. sciureus was a young adult female weighing 600 g, 92 % of the body mass of the snake and the largest prey item known to have been ingested by a C. hortulanus specimen was 1620 mm in length (SVL) and weighed 650 g, while the S. The snake was encountered at 20:00 hours on the ground next to a stream, at the final stage of ingesting the monkey. The event was recorded during a nocturnal herpetological survey in the Piratuba Lake Biological Reserve, in the north-eastern Brazilian Amazon. Here, we document the predation of a squirrel monkey (Saimiri sciureus) by an Amazon tree boa (Corallus hortulanus), the first record of the predation of a platyrrhine primate by this boid. Mammalian carnivores, raptors, and snakes are known predators of Neotropical primates, and most reported attacks by snakes are attributed to Boa constrictor (terrestrial boas). hortulanus may be limited to capturing small platyrrhines such as callitrichines.Ībstract = "Predation has been suggested to play a major role in the evolution of primate ecology, although reports of predation events are very rare. ![]() ![]() Predation has been suggested to play a major role in the evolution of primate ecology, although reports of predation events are very rare. ![]()
