According to Baer (1951) at least 95% of the genera have been reported from fishes, primarily the elasmobranchs. Some monogeneans also occur on the gills, or in the mouth and urinary bladder of amphibians and reptiles and even one species has been reported from the eye of the hippopotamus. The monogeneans are morphologically similar to rhabdocoel turbellarians of the family Graffillidae. They are small worms with posterior portion of the body modified to form a haptor, a disc-like structure, with hooks or suckers or both and is a powerful adhesive organ.

[edit] Monogenea
[edit] Introduction
Monogenea are almost exclusively ectoparasites of aquatic vertebrates. According to Baer (1951) at least 95% of the genera have been reported from fishes, primarily the elasmobranchs. Some monogeneans also occur on the gills, or in the mouth and urinary bladder of amphibians and reptiles and even one species has been reported from the eye of the hippopotamus. The monogeneans are morphologically similar to rhabdocoel turbellarians of the family Graffillidae. They are small worms with posterior portion of the body modified to form a haptor, a disc-like structure, with hooks or suckers or both and is a powerful adhesive organ. The anterior end bears the mouth and pharynx. The intestine may be saccate or bifid and is often branched. Excretory system is duplicate with anterior dorsolateral pore.
The worms are hermaphroditic with a single ovary and one or many testes. Eggs bear long filaments. Life cycle is simple and development is direct. The larva is ciliated and has a brief free-swimming period before it attaches to the host
Class Monogenca is divided into two subclasses (1) Monopisthocotylea with two orders and (2) Polyopisthocotylea with two orders. Sproston (1946) had listed 679 species spread over 130 genera. The number has definitely increased two fold by now.
