Pennella crassicornis Steenstrup & Lutken, 1861

Not valid. Original report from Bottlenose whales ( Hyperodon ampullatus and Ziphias cavirostris) and pelagic fishes ( Xiphias gladius , Mola mola and Naucrates ductor) in the Atlantic and Mediterranean. Original figures and description not detailed enough to separate the species from P. filosa or P. balaenoptera , both of which it closely resembles; synonym of P. filosa on fishes, of P. balaenoptera on mammals ( Hogans 1987); accepted as P. filosa ( Walter & Boxshall 2015) .
