In some species of the mesoparasitic family Pennellidae, pre-mated adult females and adult males are planktonic prior to mating in the water column (Kearn 2004; Ismail et al.
2007; Huys 2014) and Pennellidae (Boxshall 2005; Ismail et al.
Some species of Pennellidae and Caligidae require both an intermediate and a definitive host (Bush et al.
medusaeus (Wilson, 1908)) (Pennellidae) was described by Ho (1966) and Perkins (1983).
The phylogenetic trees of the families Eudactylinidae, Lernaeopodidae, and Pennellidae, when combined, generated a maximum of 27 independent contrasts between pairs of sister branches, although data on clutch size and egg size were missing for a few genera.
A new genus and two new species of Pennellidae (Copepoda: Siphonostomatoida) and an analysis of evolution within the family.
These were Eudactylinidae (Deets and Ho 1988), Lernaeopodidae (Kabata 1979), and Pennellidae (Boxshall 1986).
A contribution to the knowledge on the morphometry and the anatomical characters of Pennella balaenopterae (Copepoda, Siphonostomatoida, Pennellidae
), with special reference to the buccal complex.
