Keystone Species
Species that play an important role in maintaining the structure of an ecological community.
Sea Otter
The predation on sea urchins regulates the ecological balance between kelp production and the distribution of kelp by the herbivorous urchins makes this organism a keystone species.
Pisaster Ochraceus
Starfish affect patterns of species occurrence, distribution occurrence distribution and density in communities in which it lives which makes Pisaster Ochraceus and Asterias Forbesi keystone species.
Asterias Forbesi
Littorine Snails
Provides spatial heterogeneity and diverse habitats and thus support a highly diverse species of animals making it a keystone species.
