Gavin Naylor, a biologist at the College of Charleston in South Carolina, and his colleagues sequenced samples from 4,283 specimens of sharks and rays as part of a major effort to fill the gaps. The team found 574 species, of which 79 are potentially new, they report in theBulletin of the American Museum of Natural History1.
Naylor says that he was “flabbergasted” by the result, especially because the sequencing covered only around half of the roughly 1,200 species thought to exist worldwide.
