Family DASYRHYNCHIDAE Dollfus, 1935
Introduction
The Dasyrhynchidae are characterised by two bothridia, elongate bulbs, a craspedote scolex, with the tentacular armature of the poeciloacanthous form, that is bearing a chainette on the external surface of the tentacle, with more than eight hooks in the principal rows, and by the possession of an hermaphroditic duct in the proglottis (Campbell & Beveridge 1994). Campbell & Beveridge (1994) included a single genus, Dasyrhynchus Pintner, 1928. Earlier, Dollfus (1942) employed a broader definition which included all genera possessing two bothridia and a chainette. The genus was revised by Beveridge & Campbell (1993).
Adults are found primarily in carcharhinid and sphyrniid sharks, with the plerocerci or larval stages occurring in the body cavities of a wide variety of teleosts. Four species are recorded currently for the Australian fauna.
