    On the sand: When walking on sand dunes,be careful of any grasses and plants growing there.

  • In the shallows: On rocky shores,the shallow “tidepools” that are exposed when the tide is out,can be a great place to look for interesting marine life.
  • Near the reef: When snorkeling or diving,never touch the reef!
