In Florida Bay, strange ring typed signs are sometimes observed.
These are created by smart dolphins to feed themselves. Apparently, one dolphin swims quickly in a circle (usually counter-clockwise) herding the fish toward the other dolphins that are already lined up next to one another, forming a barrier with their bodies.
Small fish might be feard inside these circle... And they tend to escape out of circle...
Dolphins are just waiting outside circles opened their mouse.....
Dolphins get easily their feed without any swimming and fighting.....
On average, 4 dolphins participate in this feeding behavior.
