Parasites account for as much as or more than half of life's diversity ; they perform an important ecological role ( by weakening prey ) that ecosystems would take some time to adapt to ; and without parasites organisms may eventually tend to asexual reproduction, diminishing the diversity of sexually dimorphic traits.

Parasites can dull coloration of both sexes ; in males, coloration may serve as a signal of health.

Parasites whose life cycle involves the death of the host, to exit the present host and sometimes to enter the next, evolve to be more virulent or even alter the behavior or other properties of the host to make it more vulnerable to predators.

Parasites can at times be difficult to distinguish from grazers.

Parasites can get into the intestine by going through the mouth from uncooked or unwashed food, contaminated water or hands, or by skin contact with larva infected soil, they can also be transferred by the sexual act of anilingus in some cases.

Parasites normally enter the body through the skin or mouth.

There, she learns that the station is swarming with organisms infected with X Parasites, virions that can replicate their hosts ' physical appearances and memories, killing them afterward.

Their group, the eponymous Supernaturalists, is attempting to kill as many Parasites in Satellite City as possible, to save people from having their life sucked out by the Parasites.

One night, the Supernaturalists stalk out a drag race, as the potential for fatal crashes, and Parasites, is large.

She says that energy discharged by the Parasites is forcing the Satellite into an incorrect orbit and causing it to fall out of the sky.

She also reveals that the method the Supernaturalists are using to kill the Parasites is only causing them to reproduce faster, increasing the problem with the Satellite.

) He is the medic of the group, and does not fight the Parasites, claiming he is a pacifist.

He is used as an example of how spotters can become terrified of their visions of the Parasites.

( 1984 ) Two new species of Acanthocephalan Parasites of marine fishes from Bay of Bengal off Purri coast Orissa.

Parasites show a high degree of specialization, and reproduce at a faster rate than their hosts.

Parasites reduce host biological fitness by general or specialized pathology, such as parasitic castration and impairment of secondary sex characteristics, to the modification of host behaviour.

Parasites are classified based on their interactions with their hosts and on their life cycles.

Parasites that live on the surface of the host are called ectoparasites ( e. g. some mites ).

Parasites evolve in response to the defense mechanisms of their hosts.

Parasites that reproduce largely to the offspring of the previous host tend to become less virulent or mutualist, so that its hosts reproduce more effectively.

Parasites inhabit hosts, which represent mobile habitat patches with dynamic spatial relationships.

Parasites infect hosts that exist within their same geographical area ( sympatric ) more effectively.

Parasites inhabit living organisms and therefore face problems that free-living organisms do not.

Parasites employ numerous strategies for getting from one host to another, a process sometimes referred to as parasite transmission or colonization.

Parasites can function like keystone species, reducing the dominance of superior competitors and allowing competing species to co-exist.

Parasites are known to drastically affect how animals behave.

Parasites most commonly target the central nervous system ( CNS ) in order to alter animal behavior.

Parasites provide an opportunity for the transfer of genetic material between species.
