Also known as southern hammerhead, kidney-headed shark, and bronze hammerhead, the Scalloped Hammerhead is a species of the Sphyrnidae family of hammerhead sharks. They are the sister species of the Carolina hammerhead (Sphyrna gilberti); they differ in terms of their number of vertebrae.
The Scalloped Hammerhead stands out due to the ‘hammer’ on its head. It is a fairly large species of hammerhead sharks but smaller than the smooth hammerheads. Their bodies are greyish brown or light grey in color, fading to white below.
They have a very high metabolic rate so they need a lot of food. They generally feast on herring, mackerel, and sardines. They also feed on cephalopods like octopus and squid. Scalloped Hammerheads may also eat smaller species of sharks like the blacktip reef shark.
Their widely spaced eyes and nostrils (on top of their special senses) play a huge part in the capture of their prey. Additionally, their wide heads enable them to sense more accurately their victims, including those buried in the sand.
Female Scalloped Hammerheads are generally larger than the males. The females can grow up to 98.4 inches and weigh 180 pounds, whereas the males measure only up to 70.8 inches and weigh 60 pounds.
