Modelling imaging performance of snake infrared sense
Several snake species use infrared-sensitive pit organs to localise prey. These sensory organs enable the snake to successfully strike prey items even in total darkness or following the disruption of other sensory systems. The pit organ has traditionally been thought to function as a pinhole camera. The need, however, to gather a reasonable amount of […]
Predatory behavior of the snake Bothrops jararaca and its adaptation to captivity
Abstract 10.1002/zoo.1038.abs Habituation to captivity is difficult for some species. Understanding the motivational elements involved in predation may ease this habituation. Seventy-one Brazilian jararaca snakes (Bothrops jararaca [Wied, 1824], Viperidae, Crotalinae) recently captured and never fed in captivity were tested for predatory behavior on rodents. Lighting was adapted to allow predatory sessions to occur during […]
