I love starfish! Sometimes you can find them in tidepools. I can spend days in delight just looking in tidepools! Dalton and I were out kayaking one summer with freinds when we saw starfish on the bottom of the ocean floor. We dove down, down, down. It was deeper than it looked, the water was murky. Everytime Dalton dove down the starfish would move, faster than you would think. We could not catch them.Facts about starfish: They are not fish. They are echinoderm, closely related to sea urchins and sand dollars.
There are about 2,000 species of Sea Stars living in all the world's oceans, from tropical to cold. Five arm varietes are the most common, but some species have 10, 20 and even 40 arms. Sea Stars are famous for their ability to regenerate limbs, and in some cases entire bodies. They are purely marine animals, you will never find them in fresh water. Averge life span in the wild: up to 35 years.
Did you know? Sea Stars have no brains or blood. Their nervous system is spread through their arms and their "blood" is actually sea water. (National Geographic)
Now shall we dance with the stars?

Very interesting. I didn't know all that. David I have seen sand dollars in the wave pools in Mexico in the evening though. Thanks for sharing. They're beautiful.
