We apologize for any inconvenience browsing our shark divers website. Shark Society is re-designing (with a helping hand from the Wwwizzards) and some of the pages are temporarily not available or not complete. Launch date for the new, 2008 season website design will be middle of February 2008. Many new features and several NEW dive locations in Mozambique and Madagascar. Stay tuned, it will be worth the waiting. In the meantime you may want to check out this Tigershark video from the Aliwal Shoal. We are not into chumming or baiting the sharks yet the producer of this video was….:( Continue reading »
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.The joint Northern Ireland-U.S. research, being published in the Royal Society's peer-reviewed Biology Letter journal, analyzed the DNA of a shark born in 2001 in the Henry Doorly Zoo in Omaha, Neb. The shark was born in a tank with three potential mothers, none of whom had contact with a male hammerhead for at least three years.The baby was killed within hours of its birth by a stingray in the same tank. Analysis of its 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."Before the study, many shark experts had presumed that the Nebraska birth involved a female shark's well-documented ability to store sperm for months. This seemed the most plausible scenario even though the sharks had arrived at the Nebraska zoo as immature pups.The lack of any paternal DNA in the baby shark ruled out this possibility.

A Great White Shark that spent four months in captivity in Monterey Bay Aquarium arrived to Cabo last week, wearing the electronic tag that had been attached to him last January. Well, at least they think he's out there by Land's End. The device floated to the surface in waters near Cabo and started transmitting. The tag was designed to pop free after 90 days. Researchers will use the help of a satellite to determine the route taken by the shark, the aquatic temperatures through which he passed and the depths through which he moved. The young male Great White was captured last August and housed in a million-gallon tank at Monterey Bay Aquarium. He grew to 6 feet, five inches and 85 kg's by the time of his release.
No worries for Cabo San Lucas visitors - the most dangerous species you will encounter in Los Cabos is the 2-legged shark. He is the one you need to watch out for!! if that fellow still hangs out he just wants his peace and an occasional seal or tuna…
