Fossil Favourite Stamp Nautilus

Strange deep-sea survivor

  • The nautilus has survived unchanged for millions of years. It’s known as a ‘living fossil’.
  • Nautiluses can be found swimming in the Indian and Pacific Oceans. But they’re rarely seen because they spend most of their time in very deep water.
  • When this nautilus was alive, its predators would have included huge monsters like plesiosaurs and ichthyosaurs.
  • To protect itself, the nautilus can withdraw its head into the shell, and close the entrance with a tough hood.
  • The nautilus swims by sucking water into its mouth and through its body, then squirting it out again through a tube. So it jet propels itself – backwards!
