Know Your Echinoderms


Echinoderm Fun Facts: 

  • Echinoderms include sea stars, brittle and basket stars, sea urchins and sand dollars and sea cucumbers. 
  • They have been around for around 500 million years.
  • Their name comes from Greek and means urchin and skin. They all have spines- some larger and sharper than others.
  • Most Echinoderms have radial symmetry- body parts are arranged around a central point. 
  • Echinoderms do not have blood- they use water to circulate throughout their body. Water also helps them move their tube feet which they use for locomotion. 
  • Some Echinoderms can regenerate their body parts. Sea stars are known for regrowing arms. 

We’ll meet some neat Echinoderms this summer at camp? Do you have a favorite? We love sea stars and sand dollars in particular.
