The purple sea urchin, along with sea otters and abalones, is a prominent member of the kelp forest community. [18] The purple sea urchin also plays a key role in the disappearance of kelp forests that is currently occurring due to climate change; [19] when urchins completely eliminate kelp from an area, an urchin barren results.
Healthy patches of kelp and schools of fish returned this summer to small sections where urchins were crushed at Caspar Cove, 160 miles (200 kilometers) north of San Francisco.
If Purple Sea Urchins eat all the kelp, other herbivores will die of starvation, and Paralabrax clathratus will surely follow, as they cannot ingest the urchins due to their spiny exteriors. [18] Another invasive species along the coast of California and Baja is wreaking havoc on Kelp Bass “recruitment,” which is when newly settled ...
The coast of Southern California is known as a source of high quality uni, with divers picking sea urchin from kelp beds in depths as deep as 24 m/80 ft. [85] As of 2013, the state was limiting the practice to 300 sea urchin diver licenses. [85] Though the edible Strongylocentrotus droebachiensis is found in the North Atlantic, it is not widely ...
For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; for example, a wasting disease in predators of purple urchins has led to an urchin population surge which has destroyed large kelp forest regions off the coast of California.

The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green. Coralline algae play an important role in the ecology of coral reefs. Sea urchins, parrot fish, and limpets and chitons (both mollusks) feed on coralline algae.
The team of divers was training in the giant kelp forests of eastern Santa Cruz Island in California’s Channel Islands National Park. Curious sea creature follows diver in kelp forest — and ...
California sheephead are ecologically valuable as keystone predators on purple sea urchins and red sea urchins, keeping them from overgrazing kelp forests. [21] Thus, where they are present, sheephead contribute to the growth and biodiversity of kelp forests, and the corresponding increase in populations of other commercially valuable fish ...
