Virginia shark's pup a 'virgin birth'

Frankie · 10-10-2008, 11:22 AM

A blacktip shark, Carcharhinus limbatus, is shown in this March 2008 file photo in the Indian Ocean off Aliwal Shoal, South Africa. Scientists have confirmed the second case of a 'virgin birth' in a shark. In a report in The Journal of Fish Biology, scientists said DNA testing proved that a pup carried by a female Atlantic blacktip shark in the Virginia Aquarium & Marine Science Center contained no genetic material from a male.

Thanks BigAl for the heads up!

That's Mother Nature trying to help one species (Carcharhinus limbatus) over-come some of the problems another species (Homo sapiens ) have caused. GO Mother Nature

that is really cool! Maybe there is still hope for our oceans...

Parthenogenesis in sharks, cool.

We just learned about that in vertebrate zoology. Unfortunately that's a last ditch effort to spread their genes. I thought the new pup would be sterile, no?

hmm I just got a glimpse of an article on it. Saying its the second time known that a shark has had a-sexual reproduction I think the other was a hammerhead.

seafansar · 10-11-2008, 05:08 PM

Yeah they've recorded parthenogenesis with a hammerhead too. There's a report about it in Biology Letters: Chapman et al. 2007. Virgin Birth in a Hammerhead Shark. Biology Letters. 3: 425-427.
