According to scientists reef sharks have dropped sharply near populated islands in the Pacific Ocean. The survey by the University of Hawaii showed that the numbers were drastically lower near populated islands in Hawaii, the Mariana Archipelago and American Samoa, compared to more pristine, remote areas in the ocean. As said lead author Marc Nadon from the Joint Institute for Marine and Atmospheric Research at the University of Hawaii they estimate that reef shark numbers have dropped substantially around populated islands, generally by more than 90 percent compared to those at the most untouched reefs.
Researchers have discovered a new, as of yet unnamed, species of shark. It looks just like the scalloped hammerhead shark, curtailing efforts to save that endangered species. As said researchers at Nova Southeastern University in Florida the new look-alike hammerhead species, first discovered off the eastern United States, has been found more than 4,300 miles away near the coast of southern Brazil proving the unnamed species is widespread.
During the year 2011, more than 140 new species have been discovered, California Academy of Science reports.
