Flukeworm life-cycle. Computer illustration showing the life-cycle of a typical fluke (class Trematode) worm. The young of this parasitic flatworm infects a mollusc,such as a snail (right),before passing to an insect carrier (ant,lower left) that feeds on the mollusc. This insect is then eaten by a larger animal (the definitive host),passing the fluke to that animal,where it reproduces and lays its eggs. Here,a cow accidentally ingests the ant whilst grazing (top) on grass (left). The fluke eggs are then passed out in the animal faeces (top left) and the cycle repeats itself | |
