The term 'Laughing African Beasts' refers to hyenas, which are carnivorous mammals native to Africa and parts of Asia. Hyenas are known for their distinctive vocalizations, which sound like laughter. They are social animals that live in large groups and hunt together. Hyenas have powerful jaws and sharp claws, making them formidable predators. They are also scavengers, feeding on the remains of other animals. Hyenas are an important part of the African ecosystem, helping to keep the balance of nature.
