The bizarre appearance of these sea creatures make them the most easily recognizable of all sharks. Hammerhead sharks earn their namesake from their heads' flat, hammer-like shape, significantly increasing the distance between their eyes. Many different species features this distinctive hear shape, and some can reach nearly 20 feet and weigh over 1,200 pounds. The intimidation factor of hammerheads is multipled when they swim in large schools, making them one of the most imposing forces in their ocean home.
The hammerhead's unusual head shape serves an essential role in enhancing the shark's senses. Not only does it allow the shark a 360-degree view of its surroundings but it dramatically boosts its electroreception abilities. These boosted senses enable the hammerhead to sweep ocean floors looking for hidden prey most other creatures would miss.
Hunting parties of sahuagin use hammerheads when tracking prey in much the same way humans use bloodhounds. The hidden quarry is quickly uncovered using the shark's superior senses, leaving it little chance of escape. Though unprovoked hammerhead attacks on humanoids are rare and don't usually lead to fatalities, these sharks can be deadly and highly perceptive foes while under the influence of sahuagin or other supernatural sources.
