Amphilinidea


Amphilinidea is the name given to an order of parasitic flatworms of the phylum Platyhelminthes. Amphilinids are Cestodes, yet differ from true tapeworms as their bodies are unsegmented and not divided into proglottids. "Amphilinids are large worms which have a flattened leaf-like body. Only 8 amphilinid species are known." "The adults are hermaphroditic. A muscular proboscis is located at the anterior end, and is sometimes very weakly developed or absent." They live in the body cavities of freshwater turtles and teleost fish as adults, and in the bodies of various crustaceans as juveniles. Apart from a little studied parasitism of sturgeon, these flatworms have very little economic importance. Biologically, they have gained attention for their potential to shed light on the phylogeny of tapeworms.
