Lyrocteis is a genus of benthic comb jellies. It is the only genus in the monotypic family Lyroctenidae.
Morphology The individuals are rather large benthic ctenophores (up to 15 cm) in the shape of a lyre. They have a basal body and two curved outgrowths, from which the fishing filaments emanate, which they use to capture their planktonic food.Lyroctenidae Lyrocteis.
