A type of parasite that lives inside the body of another organism, often in its internal organs or tissues.
The doctor explained that the endoparasite could cause various health issues for the host.
Endoparasite → It is formed from "endo-" (from Greek "endon", meaning within) and "parasite" (from Greek "parasitos", meaning one who eats at another's table). The word "endoparasite" refers to an organism that lives within another organism, deriving nourishment from it.
Think of an organism living 'within' ('endo-') another organism and 'feeding off' ('parasite') it — that's what an endoparasite does.
