| In all squamates, including iguanians, the tongue is also used for vomeronasal chemoreception. |
| All animals and microorganisms such as bacteria exhibit this latter type of chemoreception, but the two commonly recognized chemosensory systems are the senses of taste, or gustation, and smell, or olfaction. |
| Owing to its participation in two separate functions, feeding and chemoreception, the tongue is the locus of a clear functional trade-off. |
| However, biochemically, this receptor plays a role in chemoreception. |
| Their styles of hunting rely on acute vision and extremely sensitive chemoreception to cover what are typically huge areas relative to their size. |
| The following article discusses the role of taste and smell and the interaction of these two sensory systems in chemoreception. |
