Extract

The common dogfish (Scyliorhinus canicula L.) is caught regularly at Plymouth and is parasitized by two monogeneans, the gill-parasitic polyopisthocotylean Hexabothrium appendiculatum (Kuhn, 1829) Nordmann, 1832 and the skin-parasitic microbothriid Leptocotyle minor (Monticelli, 1888) Gallien, 1937. Unsuccessful attempts have been made to hatch the larvae of both of these parasites, e.g. Euzet (1957) and Wiskin (1970) for H. appendiculatum, and Llewellyn (1963) and Kearn (1965) for L. minor. Euzet (1957) and Kearn (1965) found that larvae developed within the eggs of H. appendiculatum and L. minor respectively but that these larvae failed to hatch.
