Abstract Certain microphagous fishes possess an epibranchial organ (EBO), a paired muscular pocket‐like structure in the posterior pharynx, that facilitates aggregation of small food items entering oropharyngeal cavity. Morphologically complex and phylogenetically diverse, anatomy EBOs has been described number taxa this structure, many cases without thorough investigation at microscopic ultrastructural level. Additionally, evolution not rigorously examined within phylogenetic comparative context, leaving unanswered questions about how morphological diversity relates to historical patterns ecology. We characterized anatomy, histological architecture, structural 13 otomorphan species belonging orders Clupeiformes, Gonorynchiformes, Characiformes; sampling includes Cetengraulis edentulus, Nematalosa come, Tenualosa thibaudeaui , which presence EBO previously documented. then conducted preliminary relationships between phylogeny, diet. Patterns anatomical were best explained by variation along five axes: shape, size, associated gill rakers, muscularity, adiposity. consisted bilaterally diverticula surrounded layers circumferential longitudinal muscle varying amounts adipose tissue. Papillae found epithelium lining diverticulum each organ; they varied length width proximodistal axis studded with mucus‐producing cells. was strongly correlated relatedness but moderately diet some instances. hypothesize have independently evolved Otomorpha multiple times via conserved developmental pathway makes use same underlying tissue types construct morphologically diverse structures. These findings suggest there are ways build using basic components achieve functional goal—the prey.
