California’s underwater kelp forests have been almost diminished following an explosion in urchins that eat the kelp, and that is due to a decline in sea otters that eat the urchins.
This is threatening the natural food chain of the area, which could completely collapse if great whites have no source of prey.
Bryan Franks, a Jacksonville University doctoral professor said in 2019: “I can say with certainty you would lose stability, but there are so many factors involved it’s difficult to predict.
“Their prey would go up, then that third-level species would be depleted, but it’s difficult to model.
“The classic example is the otters, the urchins and the kelp.”
