This video footage highlights the ecosystem dynamics between a ray and Bar Jack (Caranx ruber). The Bar Jack is a benthopelagic predator, meaning it takes food from mid-water to the ocean floor. In this footage, the ray was feeding and the bar jack decided to join it for a ride and eat the scrapes of food the ray lets go as it continues to hunt for clams or other benthic prey. Do you think this is a symbiotic relationship? A symbiotic relationship is when two or more biological species benefit from each other.
