* Rodents: Many rodents are herbivores, like rabbits, squirrels, chipmunks, hamsters, and guinea pigs.
* Others: Elephants, horses, zebras, rhinoceroses, and hippos are also herbivores.
Birds:
* Seed-eaters: Finches, sparrows, parrots, and pigeons are examples.
* Fruit-eaters: Toucans, parrots, and hummingbirds often eat fruits.
* Grazers: Ostriches and emus are large birds that graze on grasses.
* Leaf-eaters: Some birds, like the hoatzin, eat leaves.
Insects:
* Grasshoppers, crickets, locusts, and caterpillars are all herbivorous insects that eat leaves and plants.
* Aphids feed on plant sap.
* Beetles like the Colorado potato beetle are specialized herbivores.
Reptiles:
* Iguanas, tortoises, and some species of lizards are primarily herbivorous.
Fish:
* Many species of fish are herbivores, eating algae, seaweed, and other aquatic plants.
This is just a small sample of the many herbivorous animals that exist. There are thousands of different species of herbivores, all with unique adaptations for consuming and digesting plants.
