Fasciola hepatica (Fluke) Fluke worms are a member of the Platyhelminthes phylum. They are a type of flatworm, and there are more than 10,000 species of flukes in the world today. They exist worldwide, and range in size from about 5 millimeters (0.2 inch) to several centimeters. Most of them do not exceed 100 millimeters (4 inches) in length.
Fluke worms do not have a circulatory system. They obtain nutrients by latching onto a host and living off of that host. Its organs obtain nutrients through diffusion. The fluke worm holds onto its host with a series of suckers or latches. Flukes are a parasitic animals and will usually have two hosts during its lifetime( an invertebrate and a vertebrate). |
