5 Terrifying Mermaids in Legends Around the World

3. Iara from Brazilian Mythology

She is a beautiful, immortal woman with long greenish hair, light brown or copper coloured skin and a lower body of a fish or serpent. She also has a great voice which she uses to lure men towards her.

The Iara would be found sitting on a rock by the river and comb her hair while basking under the sun. The men she enchanted would be persuaded to leave everything he has and come with her into the river where she promised he would live like a king while she caters his every need.

Is that the truth? We would never be sure of it, because for all we know, she could eat them when no one is watching. But lore has stated that the men would be catered for the rest of their life.

Their long or short life.
