Polymorphidae
Sign in to saveThe 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 Polymorphinae 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.

Les Polymorphidae sont une famille d'acanthocéphales. Les acanthocéphales sont des vers à tête épineuse, c'est-à-dire de petits animaux vermiformesés. Ils sont parasites de vertébrés et sont caractérisés par un proboscis rétractable portant des épines courbées en arrière qui leur permet de s'accrocher à la paroi intestinale de leurs hôtes.
