Prey chemical discrimination and strike-induced chemosensory searching in lizards: Their absence in a crotaphytid lizard (Crotaphytus collaris) and a proposal for research in zoos

Abstract 10.1002/(SICI)1098-2361(1996)15:33.3.CO;2-5 Lizards in seleroglossan families of actively foraging carnivores and the herbivorous iguanids use the tongue to gather chemical samples to detect, identify, and locate food prior to attack, and to relocate lost food. In contrast, previously studied iguanian families other than Iguanidae lack lingually mediated prey chemical discrimination (PCD) and do not exhibit […]
