The width of their “hammer” is 20 to 30 percent of their entire length. The are usually a brownish gray dorsally shading to white ventrally.

They are generally non-aggressive towards humans but should be left alone. Like all sharks, they have a cartilaginous skeleton and rough skin. The eyes of the scalloped hammerhead are located on the ends of its “hammer”. This gives them a better visual range than most sharks. The “hammer” also seems to be a sensory device.
