In some cases they"re inconspicuous, but in other cases they"re not. Inslavery parasite (ie. horse-hair worm) get ingested, take control of the organism, eats its insides and then come out of its anus. Parasitic wasp injects spider w/ larva and chemical causing the spider to build cocoon web for its larva to live in before hatching. So invite host to keep living on. (cid:120) degree of harm varies widely: compare: the fungus that causes athlete"s foot, and yersinia pestis, the bacterium that causes the plague. In general you they let the host live for a while, but there can also be some very lethal parasites too, especially pathogens. Live history is often really what determines the success of organism in terms of how they reproduce and disperse. Parasites typically feed on only one or a few host individuals.
