Surface morphology and distribution of oropharyngeal taste papillae in sharks and rays (Elasmobranchii, Chondrichthyes): Implications for gustatory sensitivity. [PDF]

open access: yesJ Anat
This study investigates the morphology, abundance, and distribution of taste papillae in the oropharyngeal cavity of a range of elasmobranchs using SEM, histology, and topographic analyses. The interspecific importance of gustation is reflected in quantitative differences in the size, density, and distribution of taste papillae, which have implications
