Echinorhynchidae, from Ancient Greek á¼ÂÃÂá¿Âýÿà(ekhînos), meaning "hedgehog", and á¿¥ÃÂóÃÂÿà(rhúnkhos), meaning "snout", is a family of acanthocephalan parasitic worms from the order Echinorhynchida. The adult worms live in the intestines of fishes, amphibians and reptiles. The family contains the following genera, organised by subfamily.
