In Greek mythology, the creature with the body of a man and the tail of a fish is known as a merman. These beings are often depicted in tales of the sea, embodying its mysteries and dangers. While similar to mermaids, mermen represent masculine aspects of aquatic lore. They are sometimes portrayed as guardians of the ocean or as beings who can be either benevolent or dangerous, depending on the context of the myth. Their depiction reflects ancient cultures' relationships with the sea and the supernatural elements attributed to marine life.
