Feeding ecology and diet

Tuco-tucos are strictly herbivorous and exhibit a generalist feeding strategy. They feed both on aerial and subterranean (root) parts of grasses, herbs, and shrubs.

They do not drink water; all the water they need is obtained from the plants they eat. They perform fecal reingestion (second passage of fecal pellets through the digestive tract) and have special kidney adaptations. Reingestion and kidney adaptations might be related to water economy and to the recovering of some particular nutrients.

Some species feed aboveground, while other species harvest the food outside and gather it into their burrows to feed.
