COMMENTS & OBSERVATIONS

Conditions were sunny but windy, with a 0.26m low tide. The seagrass beds were exposed but alas no critters were to be found within the sea grass. A search of the pools of standing water on the sand however revealed a diversity of life. Upon investigating a moon snail, movement caught our eye and a Gymnodoris was sighted. This set the focus and the searching continued, with 2 sea slug species observed. We also witnessed green worms attacking a beach worm, an anemone and lots of moon snails.
