Stars of the Sea

Stars of the Sea

We have met sea stars before, but we wanted to learn more about these amazing echinoderms at camp today!




  • There are around 2,000 species of sea stars.
  • Some species live up to 35 years.
  • They have no brains or blood. They use water throughout their vascular system. The water also helps them move their tube feet.
  • Sea stars do have simple eyes that see light and dark.
  • Sea stars have little plates of calcium carbonate to help protect them
  • These carnivores push their stomachs outside their mouths and digest their food before pulling the stomach back in the body.
  • Each arm of the sea star has around 15,000 tube feet. These feet secret a glue like substance to help them attach to rocks.
  • Some sea stars- like the sun star, can have up to 50 arms and weigh 11 lbs.
  • Like their relatives the brittle stars, they can regenerate arms.


We love sea stars! They come in all sizes and colors- like pink, purple and blue! Do you have a favorite color sea star?
