In this post we will look at animals that eat only grass, or mostly grass in their diet. We will also answer the question, what are they called?
What are Animals that Eat Only Grass Called?
A graminivore is a herbivore animal that eats mostly or only grass. Remember that herbivores are animals that eat only plants.
The word graminivore is derived from the two Latin words which mean “grass” and “eat”. This is where the term grazing also comes from. To graze therefore means to eat grass.
“Grazers” are a type of herbivore and are in contrast to “Browsers” which are also herbivores. Browsers eat leaves, fruits and things up higher. Grazers on the other hand eat grass, which is lower down.
Examples of Animals that Eat Mostly or Only Grass (Graminivores or Grazers)
Here are animals that only primarily or only grass in their diet, and are thus classified as Graminivores.
Cows are animals that graze and eat a lot of grass. They do browse as well and eat plants. In dairy settings they don’t eat as high of a percentage of grass in their diet, since they are fed grains and addition to hay and grass.
Similar to cows above. Cattle eat grass as their main source of food.
Horses love to graze and eat grass and hay. They are also able to eat fruits and vegetables if that is available to them.
Hippos eat mostly grass that is found near water, and some water plants.
Bison are grazers and eat mostly grass and grass like plants called sedges.
Zebras eat almost only grass in their diet, with 90% of their diet being grass. They also eat leaves and twigs as well as shrubs when grass is not available.
