How to ID a hammerhead shark: You can tell it’s a hammerhead by the way that it is! Now that you know how to spot a hammerhead, let’s get into the question on everyone’s mind. “Why does it look like that?” The short answer is surface area. Like all sharks, hammerheads have an electrosensory organ spread across their head, called the Ampullae of Lorenzini, which allows them to sense electric currents. That wide head gives them more surface area to sense stingrays in the sand and pin them down once found. That eye placement also means they get to enjoy a 360-degree field of view, perfect for spotting food and avoiding predators. Both great (like this one) and scalloped hammerheads are critically endangered due to a steep decline in population, over 90% in some areas, in less than a century due to overfishing and bycatch.
