Moon Jellies and a Box Jelly

Saw two groups of Moon Jellies, all very active, on both sides of the harbor surrounding the Harpa. Group on the outside was about 10, group on the inside was 12-20. One Box Jelly was with the group on the inside of the harbor. Box Jelly was classically square, a little long, with lines down the box angles, and I couldn't see tentacles but it was a distance of 10 feet or so.
