The Spotted Linckia (Linckia multiflora) can shed an entire arm as a method of reproduction; the arm then grows into a complete sea star, while the original sea star regenerates the missing arm and is “as good as new.”

This sea star was photographed at night in about 25 feet of water inside a lava tube off the south Kohala Coast near the Mauna Lani Resort on the Big Island of Hawaii.
