Excellent Dive at Pescadero Point's "Fire Rock" Wednesday, July 27, 2016

Greg Hoberg and I took advantage of a second day of calm seas to make a morning dive at Pescadero Point's "fire rock" - so named for the incredibly colorful invertebrate life that is so dense on the rocks there.  We were pleased to see that there is a dense kelp bed starting to regrow next to the wash rock - it is still only a small fraction of what is normally found at this site.  On the dive we still saw quite a number of urchins but we also saw many leather, spiny, and bat sea stars.  On the rocks we could see huge numbers of Acorn barnacles, frequently heavily encrusted by strawberry anemones but I also observed lots of fresh empty shells of Acorn barnacles, predated by sea stars.  Below are some pictures from our dive, to see more, please go to:  https://plus.google.com/photos/110159573286645489662/albums/6312855374239788577?authkey=CLP-nYjYg_mVyAE

After our dive we cruised offshore of Point Pinos and were entertained by bow wave riding Pacific White Sided Dolphins and Humpback Whales.

   Cocherell's Dorid Nudibranch is about 3/4 of an inch long, spotted by Greg.

                                A sculpin on the left center of the sea star, blends in well with the sea star.

  Can you spot the sculpin?  Look carefully at the right side of the strand of kelp.
