Lobster (Homarus americanus), a new host for marine horsehair worms (Nectonema agile, Nematomorpha)

  • Andreas Schmidt-Rhaesa (a1), Gerhard Pohle (a2), Julien Gaudette (a3) and Victoria Burdett-Coutts (a3)

Nectonema species are parasites of decapod crustaceans and the only known representatives of the otherwise freshwater/terrestrial taxon Nematomorpha. We report the American lobster, Homarus americanus, as a new host for Nectonema agile, a first record among astacidean decapods. A female, about 590 mm long, was found in the body cavity of one female lobster specimen. We assume lobster to be a very rare host for Nectonema.
