The sea star you point out also eats urchins. But the Sun Star Pycnopodia is a better predator of them. Otters love healthy purple urchins. But urchins in deforested areas are low in nutrients. Commercial Urchins Divers avoid barrens for lack of roe, per fish and game in SB 1980s
Jeez not a single red I could see. Those purples are parasitic to macrocystis without a predator. The starfish isn't enough to keep their population in check.
