one of the parthenogenetic generations of the digenetic flukes, or trematodes, which parasitizes an intermediate host (mollusks). The redia develops in the body cavity of the worm’s first parthenogenetic generation, the sporocyst. It in turn produces the cercaria, the larvae of the sexually mature flukes. Unlike the sporocyst, the redia has a mouth opening, a pharynx, an intestine, and a birth pore.
