Coypu: Myocastoridae

South American coypus are omnivores, meaning they eat both plants and flesh, although they eat mostly plant material. Coypus in other parts of the world are herbivores, meaning they eat only plants. Their diet consists of a wide variety of plants and plant material, including aquatic plants such as rushes, arrowhead, smartweed, reeds, cattail, bullwhip, alligator weed, and duckweed. They also eat plant leaves, stems, roots, bark, clover, and cultivated crops such as sugarcane, sugar beets, and soybeans. On occasion, coypus in South America will eat insects, mussels, snails, mollusks, and earthworms.
