Turkish children living shanty towns have higher prevalence than those in school provide apartments, with similar infection rates between boys and girls. [5] In rural Mexico, 25% of the children aged 6–10 in twelve schools were infected with H. nana. Socio-economic factors and lack of parent education are strong influences on the high ...
Platyhelminthes (from the Greek πλατύ, platy, meaning "flat" and ἕλμινς (root: ἑλμινθ-), helminth-, meaning "worm") [4] is a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates commonly called flatworms or flat worms.
Physical characteristics [ edit ] "External anatomy: Flatworm with irregular and variable color pattern characterized mainly by a cream background mottled with orange, and pink and purple-red dots concentrated medially forming an elongated blotch.
The divided flatworm can reproduce both asexually, by dividing itself, and sexually. The species is a hermaphrodite, meaning that they have both male and female reproductive organs. When two flatworms reproduce they battle to decide who gets to fertilize and who is fertilized. The winner gets to act as the male, fertilizing the other. [1]
The portion of the body closest to the prey is the portion the flatworm utilizes to grip the prey and ingest into its midventral mouth. [1] If the flatworm has been starved, it will lunge at the prey, grip onto it, and quickly ingest it. [1] However, if the flatworm is fed daily, it attacks normally and ingests at a slower rate. [1]

Pseudoceros canadensis, commonly known as the Puget flatworm, is a species of free-living flatworm in the genus Pseudoceros, belonging to the family Pseudocerotidae. Physical characteristics [ edit ]
Monogenea are Platyhelminthes, so are among the lowest invertebrates to possess three embryonic germ layers—endoderm, mesoderm, and ectoderm. In addition, they have a head region that contains concentrated sense organs and nervous tissue (brain). Like all ectoparasites, monogeneans have well-developed attachment structures.
