Animals migrate long distances without getting lost by using a combination of biological factors and environmental cues. They may rely on their keen senses of sight, smell, and hearing to navigate their surroundings. Additionally, many animals are able to detect the Earth's magnetic field and use it as a navigational tool. Some species also have the ability to remember landmarks, stars, or specific scents along their migration routes. Overall, animals have evolved various mechanisms to successfully navigate long distances during their migrations.
