The new species 【S2】______to be rare and lives off the South Carolina coast. Classified under the genus sphyrna, will be called the "cryptic species" for the time being.

They found that genes in the mitochondrial(线粒体) DNA—the DNA passed from mother sharks to their【S4】______differed significantly among sharks that were【S5】______as scalloped (有圆齿的) hammerhead sharks.
The studies also【S6】______that another independent genetic marker differed【S7】______between the two groups of scalloped hammerheads. Scalloped hammerheads are common along the coast and sharks of the cryptic species were found from Florida to Ninth Carolina. The newborn cryptic sharks, however, were found mainly along the South Carolina coast.
"The apparent abundance of the cryptic species in coastal South Carolina could be a result of sampling, but it might also【S8】______the fact that the South Carolina bays axe the more important nursery grounds for the cryptic species," Quattro said. "If South Carolina’s waters are the primary nursery grounds for them and females gather here to【S9】______, these areas should be conservation【S10】______."
A) obviously B) priorities C) proved D) evidence
E) reproduce F) genetically G) generate H) highlight
I) archeology J) offspring K) biology L) revealed
M) classified N) appears O) substantially
