mormyroid (plural mormyroids)

  1. Any freshwater elephantfish (family Mormyridae).
    • 1991, Barrie G. M. Jamieson, Fish Evolution and Systematics:
      The simple anacrosomal aquasperm of the notopteroid Papyocranus afer, the African Knife Fish, appears to be a plesiomorph condition, contrasting with the apomorphic, aflagellate sperm of mormyroids, but does not in itself necessitate exclusion of the mormyroids form the Notopteroidea in which Greenwood (1973) placed them.
