How wide is a hammerhead shark?

Answer 1

The biggest of the 9 hammerhead shark species is the great hammerhead.
The average great hammerhead shark is up to 11.5 feet (3.5 m) long. The largest reported was 20 feet (6 m) long. These large sharks average about over 500 pounds (230 kg) but can weigh as much as 1,000 pounds (450 kg). The width isn't listed but looking at pictures it seems the "hammer" width is about a third of the body length. Hope that helps.
