What a Field Day!

DSCN2168On August 6th our Reef Team surveyed two sites.  The second site, the Clam Hatchery, was definitely the highlight of the day.  The 30-meter visibility left us in awe as we surveyed the reef.  Clams were abundant and there were huge bommies covered with various types of coral.  It was amazing to see cryptic clams living within coral.  The clams camouflaged with the coral so well the snorkeler counting invertebrates had to move their hand over the rock to generate a shadow.  If a clam was hiding there, it would clamp closed its shell/retract its mantle from the diver-generated shadow, confirming it was indeed a clam rather than a rock.  The larger clams seemed to stay on the bottom while the smaller clams were on the reef.
