Shirley’s Tide Pool Experience

starfishI had a wonderful time in Half Moon Bay Fitzgerald Marine Reserve tide
pools last week. Below is a picture of a starfish I found. For the
trip, I learned about Barnacles and here are a few facts about them:
•       Barnacles are encrusters, which means they are attached to a hard substrate
•       They are suspension feeders and get food by rhythmically beating
their feather appendages to draw plankton
•       They absorb O2 through their limbs and inner membrane
