Female sharks capable of virgin birth

I love me some non-sperm births.

Female sharks can fertilize their own eggs and give birth without sperm from males, according to a new study of the asexual reproduction of a hammerhead in a U.S. zoo.

Analysis of the baby shark's DNA found no trace of any chromosomal contribution from a male partner. Shark experts said this was the first confirmed case in a shark of parthenogenesis, which is derived from Greek and means "virgin birth."

"The findings were really surprising because as far as anyone knew, all sharks reproduced only sexually by a male and female mating, requiring the embryo to get DNA from both parents for full development, just like in mammals," said marine biologist Paulo Prodahl of Queen's University of Belfast, Northern Ireland, a co-author of the report.

Female shark's have a well-documented ability to store sperm for a lengthy period of time. The lack of any paternal DNA in the baby shark ruled out this possibility.

Yea for them sharks gettin it on...with themselves.
