That's known as a'parasite'.
Scavengers
A parasitic organism usually feeds on a larger organism without killing it. Examples include leeches, ticks, and some types of parasites that live in or on larger animals like mammals or birds. These organisms obtain nutrients from their host without causing immediate death.
This relationship is called parasitism. In parasitism, the smaller organism, known as the parasite, derives benefits at the expense of the larger organism, referred to as the host. Parasites may live on the surface of the host (ectoparasites) or within the host's body (endoparasites), often leading to harm or disease in the host.

Fleas and ticks, and other paracites can usually feed of animals without killing them. I know this answer isn't good, but ain't it better than the last?
