More low light predator-prey observations. In the wide version, there are 11 sharks all converging onto one location. Why? Possibly because of the abundance of rays at this site. Notice the interaction between not only the sharks but the rays as well. At one point 4 sharks converge into close proximity to each other, all the rays react, and two sharks nearly engage. Watch closely, there's tons going on here. Very fascinating stuff once the sun goes down.
