Caplin Rous Capybara

Capybara gestation is 130–150 days and usually produces a litter of four capybara babies, but may produce between two and eight in a single litter. Birth is on land and the female will rejoin the group within a few hours of delivering the newborn capybaras, who will join the group as soon as they are mobile. Within a week the young can eat grass, but will continue to suckle - from any female in the group - until weaned at about 16 weeks. Youngsters will form a group within the main group. Alloparenting has been observed in this species. The rainy season of April and May mark the peak breeding season. Like other rodents, the front teeth of capybaras grow continually to compensate for the constant wearing-down from eating grasses; their cheek teeth also grow continuously. When fully grown, a capybara will have coarse hair that is sparsely spread over their skin, making the capybara prone to sunburn. To prevent this, they may roll in mud to protect their skin from the sun.
• Activities
Capybaras are excellent swimmers and can survive completely underwater for up to five minutes, an ability they will use to evade predators. If necessary, a capybara can sleep underwater, keeping its nose just over the waterline.
During midday, as temperatures increase, they wallow in water and graze in late afternoons and early evenings when it is cooler. They sleep little, usually dozing off and on throughout the day and grazing into and through the night.
