Whereas the criterion 'Does the enemy attack more than one victim?' separates predators from parasites, criteria that help distinguish among parasitic life-history strategies are (1) does the enemy eliminate victim fitness, (2) does the enemy require a victim's death? and (3) does the enemy cause intensity-dependent pathology? Predators can also be subdivided into useful categories by applying the first and third criteria. The next sections describe common types of parasite life histories.
