Another rather unsatisfactory image from same MLSSA dive @ Trimmer Pde end of Lakes with a number of bluish many-armed things in upper field growing(If animate) on heavily epibiota-laden cable and rope anchoring a marker buoy to substrate. They look like sea-stars but I do not know what they actually are.
Seasonally very common this jetty.Partial die-off in warm season,not converse.
IDing the fish in the middle, in the foregound looking towards the right side of the image
