An animal that feeds primarily on grass; an herbivore that specializes in eating grass plants.
From Latin 'gramen' (grass) plus 'vorare' (to devour). This scientific term directly parallels 'herbivore' but specifically indicates grass-eating behavior.
Cattle, horses, sheep, and zebras are all graminivores—they have special stomachs with multiple chambers to digest tough grass fiber that would just pass through most animals!
