Cownose Ray Evolution
Although evidence has shown that there is a recent change in the increase of the cownose ray that has caused a large boom, it's Well known that the cownose ray is a predator of shellfish when the water becomes warm. The marine systems caused by the removal of sharks remain misleading, due to the significant declines in large coastal sharks in the northwest Atlantic Ocean, which caused dramatic increases in abundances of smaller elasmobranchs (referred to as “Macropredators”) over the predation release. The large coastal sharks decline allegedly led to an order of large scale increase in the population of Cownose rays. Thereby the ever-increasing feeding of the cownose ray has led to the concerns for the shellfish populations along the U.S.
