Parasites.
Animals that live on other animals aren't always parasites. It depends on the type of symbiosis is taking place; commensalism (the animal obtains food and shelter from the other animal without hurting or helping it), mutualism (both animals benefit, sort of a 'you scratch my back i'll scratch yours' kind of thing), and parasitism (the name speaks for itself).
This is known as a symbiotic relationship, where one organism lives in or on another organism. The organism living within is called an endosymbiont (e.g., bacteria within the human gut), while the organism living on the surface is an ectosymbiont (e.g., barnacles on a whale).
A living thing that produces another living thing like itself is called a parent.
Any living being is called an organism. Organisms are individuals that display the characteristics of life, such as growth, reproduction, and response to stimuli.
An organism that kills and eats all or part of another organism is called a carnivore.
Organism is another term used to refer to a living thing.
