Table 2 Infection statistics for the ectoparasites and epizoics recovered from one lateral flank and the fluke of each common minke whale, Balaenoptera acutorostrata Lacépède, 1804, (n = 185) landed in Icelandic waters during the period April to September 2003-2007

From: Epibiotic macrofauna on common minke whales, Balaenoptera acutorostrata Lacépède, 1804, in Icelandic waters
