This is due to their low-energy diet of eucalyptus leaves, which are difficult to digest and provide minimal nutrition. To conserve energy, koalas rest for extended periods. Their slow metabolic rate and low activity levels help them survive on this nutrient-poor diet. The long hours of sleep also reduce the risk of predation, as they are less active and more likely to be hidden from potential threats.
364. How do wolves hunt in packs?
Wolves are skilled hunters, and hunting in packs gives them a significant advantage. By working together, they can take down prey that would be too large or difficult for a single wolf to capture. Wolves use strategic coordination and communication within the pack to surround and exhaust their prey. Each wolf plays a role in the hunt, with some wolves driving the prey toward others or blocking escape routes. The pack's cooperation ensures a higher success rate in capturing food, especially in challenging environments.
365. Why do cats knead with their paws?
Cats knead with their paws, a behavior that originates from kittenhood. When kittens nurse from their mother, they knead their mother's belly to stimulate milk flow. Adult cats retain this behavior as a comforting instinct. Kneading can indicate contentment and relaxation, and cats often knead on soft surfaces like blankets or their owner's lap. It may also be a way for cats to mark territory, as they have scent glands in their paws that leave behind a scent when they knead.
