According to an April 2012 article in the scientific journal Marine Biology, the new look-alike hammerhead species has now been discovered more than 4,300 miles away near the coast of southern Brazil. This confirms that the original finding was not a local oddity and the new species is much wider spread. The look-alike species may face the same fishery pressures as the real scalloped hammerhead, which is being fished unsustainably for its highly prized fins.
"It's a classic case of long-standing species misidentification that not only casts further uncertainty on the status of the real scalloped hammerhead but also raises concerns about the population status of this new species," says professor Mahmood Shivji, Ph.D., who oversaw the new research at the NSU-OC's Save Our Seas Shark Center USA and Guy Harvey Research Institute.
