People have always believed in mermaids. First of all, mermaids were considered to be not so good creatures. Some people believe that mermaids, if they meet at night some stranger near the water, they will draw him to water and tickle to death. Mermaids have been always treated with respect. Mermaid tattoos are considered to symbolize the constant growth and fertility, forests and rivers. Different mermaid tattoo designs can at the same time have opposite meanings, for example – joy and sorrow, luck and bad luck and so on. Mermaids usually are depicted with green hair.
