- Species: ZipcodeZoo has pages for 62 species and subspecies in the Order Aspidogastrea.
The Rugogastridae are a taxonomic family of flatworms that consist of a single genus, Rugogaster, with only two species. The rugogastridae are parasites, and infect the rectal glands of various species of sh. The family, genus and two species are characterised by a single row of rugae (transverse thickenings of the body surface), numerous testes, and two caeca. Species of the other three families of Aspidogastrea have a single caecum and either one or two testes. [more]
Stichocotylidae is a monospecific family of flatworms comprising the single species Stichocotyle nephropis, which is an internal parasite of elasmobranch fish, originally described from the Norway lobster, Nephrops norvegicus, by J. T. Cunningham in 1884. This flatworm is distinguished by a single ventral row of well separated suckers. [more]
