COMMENTS & OBSERVATIONS

Sightings were a little slow at first as we swam upstream about 30 metres before descending. Our latest species, Cratena sp. 07, first sighted at the Toilet Block two days previous, was present at this site as well. A single specimen of the uncommon Goniodoridella sp. 03 was recorded being the fourth sighting here. We note that only a single species type of Unidentia was sighted.

Our Historical data:
– 84 surveys conducted at this site since 08/03/2014.
– 219 species recorded by us at this site.
Flabellina rubrolineata also has a high level of sightings but we have since split them between F. rubrolineata and F. lotos so that number may be skewed.
