Great hammerhead sharks apparently don’t have a good concept of etiquette when it comes to fishing. The fishermen in the video above were attempting to land a tarpon near Boca Raton, Florida, when a great hammerhead showed up and seized their catch.

This isn’t the first time a video like this has shown up on YouTube, and it likely won’t be the last. To the credit of these guys, at least they didn’t almost stick their hands in the shark’s mouth. However, it does seem at one point that one of the guy’s on the boat thought it might be a good idea to grab onto the shark’s dorsal fin in an apparent attempt to discourage the great hammerhead from eating the tarpon. Aside from the notion that grabbing any shark’s dorsal fin is probably not a good idea, the technique seemed fairly ineffective anyway.
