In the open ocean you need to be very big or very fast to survive as there is no place to hide. The Blue marlin is big and fast. It is the predator of many other medium sized predatory fish of blue waters. A hunting party of Mahi are fair game for this powerful Blue Marlin, as it explodes on the group from below, trying to pick up the slowest fish. Drama, movement, and colour! The surface is ripped apart in the Commocean.
