COLUMBIA, S.C. (AP) - A new genetically distinct species of hammerhead shark, the ninth recognized species of hammerhead, has been discovered off the South Carolina coast, scientists say.
The new species appears 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.
Joe Quattro, a biology professor at the University of South Carolina, worked with Jim Grady of the University of New Orleans and Trey Driggers of the National Marine Fisheries Service in making the find.
Quattro discovered the new species while studying along the coast with biologists from the South Carolina Department of Natural Resources.
Quattro and his colleagues found that genes in the mitochondrial DNA — the DNA passed from mother sharks to their offspring — differed significantly among sharks that were classified as scalloped hammerhead sharks.
The studies also revealed that another independent genetic marker differed substantially between the two groups of scalloped hammerheads.
"This cryptic shark was genetically distinct," said Quattro, whose research was published recently in the journal, Marine Biology.
Scalloped hammerheads are common along the coast and sharks of the cryptic species were found from Florida to North 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 highlight the fact that the South Carolina bays are the more important nursery grounds for the cryptic species," Quattro said.
Something as simple as the salinity of the water might explain why the sharks prefer the South Carolina coast, said Quattro, who plans a field trip this summer to tag the cryptic sharks so scientists can learn more about them.
Because they seem to have a narrow geographic distribution, the sharks may be at greater risk for extinction.
"If South Carolina's waters are the primary nursery grounds for the cryptic species and females gather here to reproduce, these areas should be conservation priorities," Quattro said.
No lawyer jokes please. Lawyers are not sharks, the are ramoras.

Well, there it is. No drilling (ever) off the coast of SC.

Taste like chicken.
You know, it's funny ... I always hear people say things like:
"I love shark. Tastes just like chicken!"
"I love snake. Tastes just like chicken!"
"I love (fill-in-the-blank-oddball-meat). Tastes just like chicken!"
I've always wondered ... why go to all that trouble if it tastes 'just like chicken?' ;-) :)
Tricksy sharkses ;-)
I think the main trouble is, most of us aren't used to eating snake, shark, or whatever, and if we were to eat it all the time, it would start to taste like itself. :') I found that to be the case with various fruits which first came to my attention when I was in my early 20s -- they tasted like a cross between a this fruit or a that fruit, because I'd never had 'em before. The first time (so far, only time) I tasted octopus it did remind me of chicken, but definitely wasn't chicken. :')
[and the punchline is...]
Octopus definitely doesn't suck.
[rimshot!]
I heard something a while back about Patrick Kennedy being a hammerhead...
So, they have just discovered a new type of shark and it is already to go on the endangered species list? "Yesterday" it didn't exist, and today it is nearly extinct?
And it was discovered just off the coast of the US, where there certainly plenty of folks around. Maybe there are millions more hiding somewhere. After all, they weren't even know about until recently.
