New species of ancient mollusk found in South Korean waters

Scientists have discovered a new species of chiton, an ancient marine mollusk that has remained virtually unchanged for the last 300 million years. Chitons have an elongated oval shape with a shell composed of eight interlocking plates that resemble suits of armor. They are found all over Earth, from tropical waters to the polar regions, inhabiting tidal pools and the deep sea. Around 940 living species are known to science.
