The classification of a Sea Urchin is Echinoidea
An urchin barren is a marine ecosystem characterized by the dominance of sea urchins, particularly the green sea urchin, which has overgrazed kelp forests and other marine vegetation. This overgrazing leads to a significant decline in kelp, resulting in a barren landscape devoid of plant life, which negatively impacts biodiversity and the overall health of the marine environment. Urchin barrens can develop when predator populations, such as sea otters, are reduced, allowing urchin populations to proliferate unchecked.
