Others dig holes under the ground. Some even sleep high in trees or under leaves. But they all find a way to rest. Some animals in the sea sleep in strange ways. Fish sleep with their eyes open. They seem to look ahead far into the sea while they rest. Sea otters (海獭) sometimes sleep in beds of the plants that grow in the sea. This keeps them from moving away. Parrotfish (鹦嘴鱼) blow something from their mouths when they are ready to sleep. Then a bubble (气泡) will be formed around them. The bubble protects them from harm while they sleep. Some animals sleep under the ground. Chipmunks (花栗鼠) sleep curled up (蜷缩) in a ball. Their beds are made of leaves and grass. In winter, they sleep for two weeks and wake up to eat the stored food. Then they go back to sleep for another two weeks before waking up again. Some desert frogs dig underground holes during the hot, dry season. A frog may stay in its hole for months. High above the ground, monkeys find leafy places in trees each evening before they sleep. The tall trees help to keep monkeys safe during the night. Some insects even sleep under the leaf that will be their next meal. A bee may climb down into a flower to rest. When it climbs out the next morning, it is ready for work. 31.
