What problems does the sea urchin have in its habitat?

Answer 1

Sea Urchins role in the ecosystem is to provide a canopy habitat for larval, juvinile and some adult fish and invertebrates to hide and grow under until they are large enough to emerge safely. Sea Urchins are algae and detritis eaters which keep a balance in the benthic habitat by grazing on which if left can cause spikes in bacteria levels or in the case of coral reefs can smother coral. They move around and clean up the bottom. Lastly Sea Urchins are a food source for humans, fish and other animals. Sea Urchins can very easily overpopulate and if they do can wreak havoc in large areas in the ecosystem, particularly inside of Marine Reserves. Little is known about this phenomena of Sea Urchin Barrens other than that they can last for decades until a disease hits and there is a mass die off. In California, habitat restoration efforts are underway to eradicate these Sea Urchin Barrens or Urchin Dominated Areas by Santa Monica Baykeeper and the Orange County Baykeeper. It seems ironic that they would advocate for Marine Reserves in the MLPA process which in effect causes Sea Urchin Barrens that contradicts their efforts to restore the habitat that they have or about to destroy. Look on u tube for the Baykeepers videos and also for other sea urchin barrens videos.

Answer 2

Answer 3

The only problem that the sea anemone encounters in its habitat, aside from predators, is pollution. Pollution interferes with both reproduction and the exchange of oxygen.
