| prey transport kinematics in tupinambis teguixin and varanus exanthematicus: conservation of feeding behavior in 'chemosensory-tongued' lizards. | although lizards have been predicted to show extensive intraoral prey-processing behaviors, quantitative analyses of the types of prey-processing behavior they demonstrate and of their kinematics have been limited. the more basal lizard lineages (iguanians) have undergone some study, but the prey-processing repertoires of crown taxa have not been thoroughly examined and quantitative comparisons of behaviors within or among species have not been made. in this study, the prey transport behavior of ... | 2000 | 10648221 |
| predatory behavior intupinambis teguixin (sauria: teiidae). i. tongue-flicking responses to chemical food stimuli. | black tegu lizards (tupinambis teguixin) have the ability to detect food odors and discriminate between them and nonfood odors. this was tested by offering chemical stimuli on cotton-tipped applicators to the animals. stimuli were from two plant and two animal species known to be principal items in these lizards' diets, demineralized water as an odorless control, and eaude-cologne as an odorous control lacking feeding or social importance. tongueflick attack score, latency to attack, preattack t ... | 1993 | 24248875 |
