The monophyly of the Capsalidae is supported by possession of accessory sclerites in the haptor (the posterior attachment organ), and was confirmed by molecular phylogeny. Their oncomiracidium (the free larva) is distinct from that of other families.{{cite journal|last1=Lambert|first1=A.|title=Recherches sur l'oncomiracidium des Capsalidae (Monogenea)|journal=Annales de Parasitologie Humaine et Comparée|volume=53|issue=4|year=2017|pages=351–357|url=https://www.parasite-journal.org/articles/parasite/abs/1978/04/parasite1978534p351/parasite1978534p351.html|doi=10.1051/parasite/1978534351|doi-access=free}} {{open access}}

Capsalids are parasite on various organs of marine fish (teleosts and elasmobranchs), including skin, fins and gills. Several capsalid species, such a Neobenedenia spp.{{cite journal|last1=Orbán|first1=László|last2=Dinh Hoai|first2=Truong|last3=Hutson|first3=Kate S.|title=Reproductive strategies of the insidious fish ectoparasite, Neobenedenia sp.
