Ground skinks

Olfaction is not necessary in other lizard species. For instance, the ground-skink, Scincella lateralis, which feeds on insects in the ground litter, does not require chemical cues to attack prey (Nicoletto, 1985). Presumahly, vision alone suffices for this purpose.

Olfactory cues have been studied in both five-lined skinks (Eumeces fasciatus) and ground skinks Scincella lateralis) by means of an olfactometer (Duvall et al. 1980). Airborne chemical cues from conspecific males and females showed that these animals respond to the odors with tongue-flicks and snout-dips (Duvall et al. 1980). Chemical cues from heterospecific animals were ignored.

Besides squamates, some chemosensory research has been done on lacer-tilians. Duvall et al. (1980) have shown that five-lined skinks and ground...
