" The second packet of the Islands of Korea Series features the spectacular nature at Marado Island. Marado Island, at the southernmost of Korea, is breathtakingly beautiful with its lighthouse in the background. The island is short in length from east to west while curbed in an oval shape from north to south, and its base rocks are composed of whinstones. The waters surrounding the island of Marado are extremely abundant in subtropical marine plants and animals due to its geographical position. Subtropical marine plants, in particular, flourish here, exhibiting very unique flora in comparison with those inhabiting Jejudo Island and the coastal areas of the peninsula. According to a survey, a total of 72 species of plants including green algae, brown algae and red algae live around the island. As for marine animals, six species of sponge (porifera), eight types of shellfish (bivalvia), four sorts of crustacea, and other species previously unrecorded in Korea have been identified. Additionally, Sea chubs (Girella punctata), Convict grouper (Ephinephelus septemfasciatus), Japanese seaperch (Lateolabrax japonicus), Pearl-spot chromis (Chromis notata), Knifejaws (Oplegnathus fasciatus), Scorpionfishes (Sebastiscus marmoratus), Largehead hairtail (Trichiurus lepturus), Sea goldie (Pseudanthias squamipinnis) and other varieties of fish can be found. Since so many floras, which had been previously unidentified in Korea, as well as new living organisms have been discovered around the island, and its adjacent areas offer a marvelous view, the island of Marado was designated as Natural Monument No. 423 and is protected under the name of Marado Natural Monument Area."
