Mermen are mythical male equivalents and counterparts of mermaids, legendary creatures who have the form of a male human from the waist up and are fish-like from the waist down, having scaly fish tails in place of legs. The actions and behavior of mermen can vary wildly depending on the source and time period of the stories. They have been said to sink ships by summoning great storms, but also said to be wise teachers, according to earlier mythology. Mermen, just like mermaids, can lure and attract female humans with their enchantingly beautiful, soft melodic and seductive siren-like singing voices and tones. A legendary creature is an animal, especially a nonhuman, whose life is accounted in non-historical or yet to be verified stories that sometime involve the supernatural. Some legendary creatures have their origin in traditional mythology and have been believed to be real creatures.
