definitive host (final host) a host in which a parasite attains sexual maturity.
intermediate host a host in which a parasite passes one or more of its asexual stages; usually designated first and second, if there is more than one.
paratenic host a potential or substitute intermediate host that serves until the appropriate definitive host is reached, and in which no development of the parasite occurs; it may or may not be necessary to the completion of the parasite's life cycle.
host of predilection the host preferred by a parasite.
primary host definitive host.
reservoir host an animal (or species) that is infected by a parasite, and which serves as a source of infection for humans or another species.
secondary host intermediate host.
transfer host one that is used until the appropriate definitive host is reached, but is not necessary to completion of the life cycle of the parasite.

The life cycle stages of anisakid nematodes include four larval stages ([L.sub.1]-[L.sub.4]), within the eggs ([L.sub.1]-[L.sub.3]) and subsequently in the intermediate or paratenic hosts ([L.sub.3]), and as preadults ([L.sub.4]) and adults in the cetacean definitive hosts (Klimpel & Palm, 2011).
Gammarids regularly harbor manipulative acanthocephalan parasites that modify their anti-predator behavior in ways that potentially increase the probability of trophic transmission to their definitive hosts. We investigated the impact of temperature on gammarids infected by two acanthocephalan parasites, Pomphorhynchus tereticollis and Polymorphus minutus.
Environmental impacts influence the density of intermediate and definitive hosts, making them more susceptible to infections (Lafferty & Holt 2003) and giving way to an increase in prevalence and even to the pathogenicity of parasites (Holmes 1996).
