polymorphidae : ウィキペディア英語版 | polymorphidae
The thorny-headed worm family Polymorphidae contains endoparasites which as adults feed mainly in fish and aquatic birds. When this taxon was erected by Meyer in 1931, a subfamily Polymorphidae was established in it. As the Polymorphidae as presently understood would then be monotypic, with no basal genera outside the Polymorphinae, the proposed subfamily is redundant for the time being and therefore most modern treatments simply omit it. ''Polymorphus minutus'' is an economically significant parasite in goose and duck farming. ==Genera==
