1. Mammary Glands: Female koalas have two mammary glands located on their chests. These glands produce milk specifically for their joeys.
2. Feeding Position: When the joey is ready to feed, it crawls onto its mother's belly and positions itself in front of one of the mammary glands.
3. Nipple Structure: Koala nipples are elongated and protrude from the mammary glands. This specialised nipple structure allows the joey to securely attach and suckle.
4. Milk Composition: Koala milk is rich in nutrients, fats, and proteins essential for the joey's growth and development.
5. Suckling: The joey latches onto the nipple and begins suckling. Koala joeys are often seen suckling for extended periods, sometimes for several hours.
6. Milk Supply: The koala's milk supply is regulated by the joey's suckling. As the joey suckles, it stimulates the mammary glands to produce more milk.
7. Nutritional Support: The milk provides the joey with essential nutrients and antibodies, contributing to its overall growth, immunity, and health.
8. Transition to Eucalyptus: As the joey matures and becomes more independent, it begins to transition from milk to a diet consisting primarily of eucalyptus leaves. However, it may continue to suckle for comfort or supplementary nutrition.
9. Pouch Protection: The joey is typically kept safe and protected within its mother's pouch during its early stages of development. The pouch provides warmth, comfort, and easy access to milk and nurturing.
10. Gradual Weaning: The process of weaning from milk to eucalyptus leaves is gradual and may take several months. As the joey becomes more adept at consuming solid food, it gradually reduces its dependence on milk.
