Description

Undetermined Pennella sp.

A Pennella which is likely a distinct species, but has not previously been assigned to any known member of the genus has been documented. Nagasawa et al. (1984) identified a Pennella sp. from the saury (Cololabris saira) in the north Pacific. The parasite is clearly different from any of its congeners based on photographs of recovered specimens (Nagasawa et al. 1984). The cephalothoracic papillae are dendritic and form a large mass covering the entire apical end of the parasite, a feature not yet reported from any other species of Pennella. Nagasawa et al. (1984, 1988) reported on the population dynamics and geographical distribution of the parasite; the authors were reluctant to classify the specimens further than the generic diagnosis based on the poor taxonomic condition of the genus.
