The rest of the survey went very well too! We decided to carry out a transect survey along a long gully  so that it can easily be repeated in future.  Heather (www.cornishrockpools.com)  did a walkover survey in the lagoon and found stalked jellies among the eel grass! On the extreme lower shore we also found a really cool chameleon prawn. Thanks to Amelia, Micky, Cheryl, Rob, Heather and Louis, John and Jasmina who all turned out to help! It was a great day.
