  1. biologyA round lump made up of or coated with slime or a slime-like substance such as mucus.
    1. specificallybiologyA mucus-coated lump containing the cercariae (“parasitic larvae”) of a liver fluke (of the phylum Platyhelminthes).

      The eggs [of a lancet fluke (Dicrocoelium dendriticum)] that pass out with the manure of an infested sheep do not hatch in the open. When eaten by the snail, they hatch and finally give rise to larvae that pass out of the snail's body in gelatinous "slime[-]balls."

      The cercariae contain massive glands, formerly considered to be penetration glands, but now believed to produce the slime responsible for the formation of these balls. It is likely that the slime produced by the snail itself may contribute, at least partly, to the formation of a slimeball.

      These flukes have three hosts. [...] As the infected snail crawls along it leaves slime balls containing cercaria on grass. An ant, Formica fusca, the arthropod host for D. dendriticum in the United States, is infected when it ingests the slime balls. Mammals are infected by consuming ants containing encysted metacercaria.
