Crinoid

Fossil Favourite Stamp
Tropic Feather Star
Tropical feather star, similar to the crinoid but without the stalk.

Lovely lily of the sea

  • Crinoids are delicate and graceful marine animals – they’re also called sea lilies because they look like underwater plants.
  • They belong to the same family as sea urchins and starfish.
  • Crinoids don’t move much – they attach themselves to the sea bed or floating drift wood using tiny hooks called cirri. But if they’re threatened by a predator some can let go and swim by undulating their arms.
  • Crinoids feed on tiny plankton which they catch with their sticky arms.
  • Crinoids have been around for almost 500 million years and still exist today, usually in tropical waters.
  • Sometimes many crinoids are packed into one rock. This is because they lived on driftwood and when that sank, the whole colony became fossilised together.
  • See this fabulous crinoid in Lyme Regis Museum.
