University of the Pacific Theses and Dissertations
The morphology of the proboscis--particularly the epiproboscis, the feeding behavior, the function(s) of the epiproboscis, and the functional morphology of the epiproboscis, were studied in Mitra idea Melville and fi. catalinae Dall (Gastropoda: Neogastropoda; Mitridae.
In M. idae, the epiproboscis is an extensible muscular J-shaped rod which curves under the odontophore, and lies parallel to the longitudinal axis of the proboscis. A muscular external sheath encloses that portion of the epiproboscis which lies within the proboscis haemacoel; an invaginated muscular-epithelial internal sheath covers the ventral part of the epiproboscis. The dorsal part of the epiproboscis consists principally of longitudinal muscle; …
