79 New "Cryptic" Species of Sharks Discovered

At least 79 new species of sharks have been discovered by the scientists in South Carolina. Researchers at the Hollings Marine Laboratory at Fort Johnson on Charleston Harbor studied the DNA by allowing the genes to stick to the molecules. This way the researchers were able to compare the genetic coding of the 79 new species with that of the other species. They found that the newly discovered sharks are different from others and called them the "cryptic" species.
