obligatory parasite
must lead a parasitic life; not free-living
An obligatory parasite is a type of parasite that must live on its host in order to survive. It cannot complete its life cycle or reproduce without a host. Obligatory parasites are usually highly adapted to their hosts and have evolved specific traits that enable them to survive in the host’s environment.
Examples of obligatory parasites include tapeworms, which live in the digestive systems of animals and humans, and lice, which live on the body of their host and feed on their blood. Malaria is also an obligatory parasite that lives in the blood of its hosts, which are typically mosquitoes and humans.
Obligatory parasites can have significant impacts on the health and well-being of their hosts. They can cause disease, weaken their hosts, and even lead to death. In some cases, controlling or eradicating the parasite is necessary to protect the health of the host.
