Ultrastructure and functional morphology of glandular setae and distal claws of cephalic appendages of Speleonectes tanumekes (Crustacea: Remipedia)

Van der Ham, J.L. | Felgenhauer, B.E.
Terminal pores on crustacean setae are commonly associated with chemoreception. In this study we present an exception to that association with the description of glandular setae on maxillulary and maxillary endites of the remipede Speleonectes tanumekes. This introduces a function associated with crustacean setae beyond the general functions currently assigned to crustacean setae: sensory functions, mechanical functions, or a combination of these two. Even though the functions of the secretory products are unclear, we suggest means by which these may contribute to feeding behaviors. In addition, we describe glandular features of maxillary and maxillipedal distal claws of the same remipede species. Glandular setae and distal claws appear to share several morphological homologies.
