The Spotted Jelly or Lagoon Jelly (Mastigias papua) is a species of jellyfish. It lives mainly in the southern Pacific Ocean. Instead of one single mouth, they appear to have several smaller mouth openings in their oral arms. These feed on zooplankton. In Japan--especially along Pacific coast areas--these are sold as novelty pets, along with photoautotrophic phytoplankton, and are called takokurage (), or "octopod" or "rammer" jellies.
