Anales del Instituto de Ciencias del Mar y Limnología, Universidad Nacional Autónoma de México (Vol. 8, pp. 305-314). Members of Anchoromicrocotylinae differ from other

by the presence of a larval organ and larval hooks and the structure of the genital complex.

Morphology

Members of Anchoromicrocotylinae are characterized by a symmetric

haptor The haptor is the attachment organ of the monogeneans, a group of parasitic Platyhelminthes. The haptor is sometimes called opisthaptor (from ''opistho-'': behind) to emphasize that it is located in the posterior part of the body, and to diffe ...
