“…Second, we provide an overview of the anatomical features that are used in chemoreception in a range of invertebrate and vertebrate taxa. Note that many other aspects of biology influence chemosensory behavior, including genetics (Nei, Niimura, & Nozawa, 2008), biochemistry (Wyatt, 2014b), energetics (Palouzier-Paulignan et al, 2012), neurophysiology (Gabor, Phan, Clipperton-Allen, Kavaliers, & Choleris, 2012), and development (Bertin et al, 2016), and we recommend the aforementioned references as introductions to those topics. We chose to focus on anatomy because chemosensory postures are often directly associated with anatomical specializations.…”
