Capybaras are the world’s largest rodents, known for their calm nature and love for water. But what really keeps these gentle animals healthy and happy? The answer lies in their diet. If you’ve ever wondered what plants capybaras eat, or what makes up their menu in the wild and in captivity, you’re not alone.
Understanding their food preferences is key for anyone interested in capybara care, wildlife management, or simply learning about unique animals.
Natural Diet Of Capybaras
In the wild, capybaras live in South America, often near rivers, lakes, or marshes. Their diet is shaped by the wetland and grassland plants around them. Capybaras are strict herbivores, which means they eat only plant matter.
Common Plants In Their Diet
Capybaras mostly eat:
- Grasses – This is their main food, especially during the wet season. They prefer soft, green grasses.
- Aquatic plants – They spend hours in water, often eating water plants like water hyacinth and reeds.
- Herbs and sedges – These are found at the edge of water bodies.
- Bark and twigs – In the dry season, when fresh grass is less available, capybaras chew on soft tree bark and twigs.
- Fruits and vegetables – Rare in the wild, but they will eat fallen fruits when available.
Seasonal Eating Habits
Capybaras adjust their diet based on the season. During the wet season, fresh grass is plentiful. In the dry season, they eat more reeds, bark, and whatever green plants are left.
Here’s a quick look at how their diet shifts:
| Season | Main Food | Supplemental Food |
|---|---|---|
| Wet Season | Grasses, aquatic plants | Herbs |
| Dry Season | Bark, reeds | Twigs, dry grasses |
Specific Plant Types Capybaras Eat
While capybaras will try many plants, some are their favorites. Here are specific examples:
- Bermuda grass – Common in both wild and captivity.
- Sugar cane – They eat the soft stems.
- Water hyacinth – Found in ponds and lakes.
- Paspalum grass – A staple in many wetlands.
- Reeds and sedges – Such as Eleocharis and Cyperus species.
- Pondweed – Grows in shallow waters.
- Wild rice – In some regions, capybaras feed on wild rice plants.
- Corn stalks – In agricultural areas, they may graze on young corn plants.
- Alfalfa – Sometimes offered in zoos and farms.
- Melons and squashes – Eaten if available, especially in captivity.
Capybaras are not picky, but they do need a high-fiber diet. Without enough fiber, their digestion can slow down and health problems may develop.

Capybaras In Captivity: What Should They Eat?
When capybaras live in zoos, sanctuaries, or as pets, their caretakers must mimic their natural diet. The goal is to offer a variety of high-fiber plants.
Recommended foods:
- Timothy hay – A good grass substitute.
- Orchard grass – Another safe, fibrous grass.
- Leafy greens – Romaine lettuce, dandelion greens, collard greens.
- Root vegetables – Carrots, sweet potatoes (in small amounts).
- Limited fruit – Apples, melons (as occasional treats).
Avoid foods that are too high in sugar or low in fiber. Capybaras cannot digest animal protein or processed food.
Here’s a comparison of common captive foods:
| Food Type | Fiber Content | Notes |
|---|---|---|
| Timothy Hay | High | Essential for digestion |
| Romaine Lettuce | Medium | Safe, but not a staple |
| Carrots | Low | Only as treats |
| Water Hyacinth | Medium | Good for variety |
Non-obvious Insights For Capybara Diet
Many beginners make mistakes when feeding capybaras. Here are two insights that most people miss:
- Capybaras practice coprophagy – They eat their own soft feces to digest plant cellulose better and get extra nutrients. This is normal and important for their health.
- Not all greens are safe – Some common garden plants like lilies, azaleas, or tomatoes can be toxic to capybaras. Always check plant safety before offering something new.
Another important point is that capybaras need constant access to fresh water, not just for drinking but also for eating aquatic plants.

How Much Do Capybaras Eat?
A healthy adult capybara eats about 2.5 to 3.5 kg (5.5 to 7.7 lbs) of fresh plant matter each day. Their digestive system is designed for large volumes of fiber. If you’re planning to keep a capybara, be ready to supply a lot of grass or hay daily.
For easy reference, here’s a table:
| Capybara Weight | Daily Food Intake |
|---|---|
| 50 kg (110 lbs) | 2.5 kg (5.5 lbs) |
| 60 kg (132 lbs) | 3.0 kg (6.6 lbs) |
| 70 kg (154 lbs) | 3.5 kg (7.7 lbs) |
Foods To Avoid
Some plants and foods are dangerous for capybaras:
- Nightshades (tomato leaves, potatoes)
- Onions and garlic
- Chocolate and processed foods
- Houseplants (many are toxic)
- High-sugar fruits (in large amounts)
Feeding mistakes can lead to digestive upset, liver issues, or even death. When in doubt, stick to safe grasses and greens.
Capybara Feeding Behavior
Capybaras are social eaters. They often feed together, which helps them stay alert for predators. They usually graze in the early morning and late afternoon, resting during the hottest hours. In captivity, it’s best to split their food into several feedings throughout the day.
It’s also common to see capybaras gnawing on branches. This keeps their teeth, which grow continuously, at the right length.
Frequently Asked Questions
What Is The Main Plant Capybaras Eat?
Grasses are the main food for capybaras. In the wild, they prefer soft, green grasses found near water. In captivity, timothy hay is a good replacement.
Can Capybaras Eat Fruits?
Yes, but only in small amounts. Fruits like melons, apples, and bananas can be given as treats. Too much fruit can cause digestive problems due to sugar.
Are There Any Plants That Are Toxic To Capybaras?
Several common plants are unsafe. Avoid nightshade family plants (tomato leaves, potatoes), lilies, and azaleas. If unsure, always check with a veterinarian or use resources like the Wikipedia List of Poisonous Plants.
How Much Water Do Capybaras Need?
Capybaras need constant access to clean water for drinking and swimming. Water helps them regulate temperature and supports their love of aquatic plants.
Do Capybaras Need Supplements?
Normally, a varied, high-fiber plant diet provides all nutrients. Supplements are only needed if their food is limited or lacks variety. Always consult an exotic animal vet before adding any supplement.
Capybaras are fascinating grazers with unique food habits. Whether you’re caring for one or just curious, understanding what plants they eat helps ensure their well-being. Focus on a fiber-rich, plant-based diet, avoid toxic foods, and observe their natural grazing behavior for best results.
