We have a new fanimaly to share with you today! We have two animals that can be found in the intertidal zone that are related! Come learn about sea stars and sand dollars!


sand dollar

  • Sand dollars are animals! They are members of the enchinoderm family.
  • They are invertebrates.
  • Sand dollars are covered in tiny purple spines.
  • Those spines help them move and they use them as gills.
  • They have a five pointed shape.
  • Sand dollars have five teeth like projections that they use to chew their food.
  • Sand dollars can live up to 6 to 10 years.



  • Sea stars are also echinoderms.
  • Sea stars are carnivores like sand dollars.
  • They have no blood or brains.
  • Most sea stars have 5 arms, but some can have as many as 40.
  • Sea stars have tiny little feet that they use to move and to pry apart prey like muscles.
  • Sea stars push their stomach outside their body to envelope their prey and digest it.
  • They can regenerate limbs.

These are just a few fun facts about these two animal relatives. Sea stars and sand dollars are both super cool! Which one do you like best?

    I love both equally but I did happen to find an intact sand dollar last year in Washington State. It is one of my treasured finds of any kind. So beautiful… even if it does keep leaving sand all over LOL
