Herbivores are organisms that are anatomically and physiologically adapted to eat plant-based foods. Herbivory is a form of consumption in which an organism principally eats autotrophs such as plants, algae and photosynthesizing bacteria. Herbivore means ‘plant eater’ from the Latin herba meaning a small plant or herb and vorare meaning to devour.
Carnivores are organisms that derive its energy and nutrient requirements from a diet consisting mainly or exclusively of animal tissue, whether through predation or scavenging. Carnivore means ‘meat eater’ from the Latin carne meaning flesh and vorare meaning to devour.
Omnivores are organisms that eat both plants and animals as their primary food source. They are opportunistic, general feeders that are not specifically adapted to eat or digest either meat or plant material primarily. Omnivore means ‘eater of everything’ from the Latin omni meaning all or everything and vorare meaning to devour.
I would like to propose another classification of organism that is redundant and at the same time simpler than the above scientific classifications. Animavore. There are a few people who use this as “a person who eats animals,” however they are incorrect in their usage of anima to mean animal. Anima is the Lain word for life meaning animating principle (as opposed to the Latin vita meaning the whole of ones life).
Animavores are organisms that consume life as their food source. Which would include every other classification of consumers.
