Ko Nom Sao (, lit. female breast island) are twin islands in Phang Nga Bay, and are part of the Ko Panyi (à ¹Âà ¸Âà ¸²à ¸°à ¸Âà ¸±à ¸Âà ¸«à ¸¢à ¸µ) subdistrict (tambon), Phang Nga Province, Thailand.
Ko Nom Sao is a geographical feature consisting of two small islands of similar appearance located close to each other. One of them, Ko Nom Sao Yai (à ¹Âà ¸Âà ¸²à ¸°à ¸Âà ¸¡à ¸ªà ¸²à ¸§à ¹Âà ¸«à ¸Âà ¹Â), is slightly larger than the other, but from certain angles the silhouette of these islands looks like a pair of roughly identical woman's breasts.
These islands are also known as Ko Ok Meri.
