Capybara are nocturnal mammals. They sleep during the day and forage at night. Some people may think that because capybaras spend most of their time in the water, they don’t need good vision to see around them or to spot predators. This is not true. Capybaras can see well in low light conditions, just like many other nocturnal animals.
The eyelids of capybaras close when they rest or sit so they don’t let any light in. However, some light leaks through the eye and gets reflected back to the animal by a third eyelid called a nictitating membrane. It looks kind of like a small membrane with a drop of clear liquid on it, but much smaller than your eyes. This drop of clear liquid protects the capybara’s eye from damage while it is closed and also lets more light into their eye while they are awake so they can see better during the day time. The capybara uses its nictitating membrane when it wakes up after resting in water because it needs more light to see clearly for a few minutes until its eyes adjust to being out of water again.

Are Capybaras Active at Night?
Capybara are more active at night. They use their superior vision to hunt for food and avoid predators during the day time, but they sleep
Do Capybaras Sleep a Lot?
Capybaras sleep a lot because they are nocturnal animals. They sleep during the day and forage at night.
If capybaras didn’t have nictitating membranes, then their eyes would be in constant contact with water and this could lead to eye infection, blindness, or damage. So capybaras are very grateful for their nictitating membranes that protect their eyes from harm.
