Mermaids (also referred to as merpeople or mers) exist, though they are highly elusive and rarely seen, living largely in the twilight zone of the ocean and only coming near the surface at nighttime to feed. They generally avoid interaction with humans. In the past, most information about mermaids was gathered through rare sightings or by studying corpses that washed up on the beach.
