Robert Paine first coined the term keystone species after working with his sea stars in the Pacific Northwest. He observed that even though they had low abundance, they controlled the structure of the rocky intertidal community. Therefore they had disproportionate effects in the system given their abundance and were dubbed "keystone".Subsequently, the predator population decline. Some keystone prey species were found to increase the diversity of other species also. One such example is the snowshoe hares. African elephants are a classic example of keystone species which affect the species diversity of the community by their extensive destructive habits of the ecosystem. 3.The sea otters are keystone members of the marine ecosystem because they are eaters of more that 100 different types of sea species. Apart from the sea invertebrates preyed upon by the sea otters, they also eat crabs, limpets and octopuses. This illustrates that the prey of sea otters is of diverse sizes and types (Laidre, Kristin and Ronald 799).Laboratory and mesocosm experiments show that ocean acidification may affect all marine life, for example, through changes in gene expression, physiology, reproduction and behaviour [7–10].
